670fd7ad58 Implement "-mno-align-long-strings" which prevents pessimization of strings
for space.  -Os could do this, but it was easy to hack an MD version.
This saves a whole 32 bytes in boot2, so I think it is worth using it.
(keep how much worse gcc 3.2 will compile boot2...)

13696e0464 MFC: gcc.295/config/alpha/freebsd.h revision 1.12:
Remove our definition for FUNCTION_PROFILER as it is wrong.

Note that "jsr $28,_mcount" is a macro for
	ldq $27, _mcount($29)           !literal!1
	jsr $28, ($27), _mcount         !lituse_jsr!1

1. The call to _mcount is added by alpha_expand_prologue after we load the gp.
Our _mcount uses $27 for the incoming address, unlike OSF/1 and Linux,
which use $28.  This probably doesn't matter since we probably don't use $27
within _mcount itself.
2. You can't use this insn with _mcount because it uses the PLT, which clobbers
the return address in $28.  Note that the prologue_mcount pattern carefully
avoids adding the lituse_jsr relocation so that we call through the GOT
directly.

a6d80351b7 Re-initialize gp after a jsr.
When rtld runs the .fini section in a shared lib (C++), the code in
question from .../contrib/gdb/config/alpha/crtbegin.asm first calls
__do_globals_dtors_aux and then __do_frame_takedown.  Unfortunately, the
value of gp after a jsr is undefined and in this case had changed from before
the call, probably as a result of calling code in some other shared library.
The normal calling convention for alpha is to re-initialize gp using
'ldgp gp,0(ra)' after a jsr instruction but in this case no such
re-initialization is done. This leads to a bogus value being read for the
address of __do_frame_takedown and a quick segfault.

cb300ebf8e Make it easy for people to use define DWARF2 exceptions unwinding.
If "WANT_DWARF2_UNWIND" you get it.  Note that this is a different C++ ABI
than the FreeBSD default.  So you will need to recompile all your C++ apps
that uses exceptions if you turn this on.  I am adding it here for Yahoo!'s
use and for those that want to be early adopters to what I will make as the
default with the GCC 3.0 import.

49bd150d88 Move the obvious bits of mixed ELF and a.out support down into this MD
header to reduce the difference of our sources to the stock GNU/FSF ones.
While the mix binary format support was nice to have in the FreeBSD MI
header as a frame work, it just clutters up too much and makes the FreeBSD
MI header more different from the FSF/GNU stock one than it needs to be.

e09c90cd8a Bump __FreeBSD_cc_version to 500002 to show the -pthread option change. 2001-02-08 05:27:17 +00:00
John Polstra
747291735d Make the "-pthread" option work again, now that libc_r has to be
linked in addition to libc rather than instead of libc.

Ideally, "-pthread" would now be equivalent to adding "-lc_r" to the
end of the link command.  But it is slightly different in this
implementation.  Adding "-lc_r" to the link command would produce a
"ld" command line containing this:

    ... -lc_r /usr/lib/libgcc.a -lc /usr/lib/libgcc.a ...

but this implementation of the "-pthread" option produces this:

    ... /usr/lib/libgcc.a -lc_r -lc /usr/lib/libgcc.a ...

It would be possible to make them identical, but that doesn't fit
as nicely into GCC's way of doing things.  I don't think the ordering
change will make any difference in practice.

4553af7930 ASM_DECLARE_OBJECT_NAME and ASM_FINISH_DECLARE_OBJECT are ELF MI routines
to generate the special .type and .size directives which are used to set
the corresponding fields of the linker symbol table entries in the ELF
object file.  As such they are not i386-specific and thus belong in our
MI header.  Otherwise on the Alpha we don't properly give the type and
size of dynamic symbols.  Bintuil versions past 2.9.1 warn of this and
w/o this change, `ld' generates a lot of warnings during a `make world'.

c92f6a5f61 Fix our -mprofiler-epilogue code.
"The problem is that egcs/gcc-2.95's reorganisation of the prologue and
epilogue code to use rtl instead of output_asm_insn() completely broke our
hooks.  rtl is emitted in a different order, only after optimisation, while
output_asm_insn() is emitted immediately.  rtl is presumably used so that
the prologue and epilogue can be optimised.

I couldn't find any good examples to copy.  gcc's own
FUNCTION_BLOCK_PROFILER still uses output_asm_insn() and seems to be
completely broken.  One of the XXX comments points to this.

IIRC, the hacks here basically arrange to emit magic label names; then when
the magic names are output, they are transformed into prologue and epilogue
code."

92a8fe88b3 Changes for Alpha and EGCS.
*  Commonalities with i386, moved to a FreeBSD wide config file.
*  Major additions to this file were adapted from Hidetoshi Shimokawa
   <simokawa@FreeBSD.ORG>'s Alpha suppliment to the Egcs 1.1.2 port.

844dfb548c This should get us the same functionality we had with GCC 2.7.2.1.
*  Support for our dual ELF/a.out building ability
*  Our custom ASM_* definitions
*  Our custom debugger and profiling related definitions
*  Our custom STARTFILE/ENDFILE specs

*  The stock EGCS 1.1.2 freebsd-elf.h file depended on
   egcs-1.1.2/gcc/config/linux.h, which included "svr4.h".  We will
   include "svr4.h" via our "tm.h" definition.  So add the few bits
   from "linux.h" we actually needed.

*  Using our current crtbegin.o/crtend.o we cannot support the DWARF2
   unwinding mechanisms.  In the future we will switch to the
   non-sjlj-exceptions type exception machanism.  However the `make world'
   bootstrap problems with the EGCS crtstuff.c must be overcome first.

*  Our a.out gas doesn't "know" to use NOP's for aligns while in the text
   section.  Thus the a.out alignment generation needed tweaking from
   what we did with GCC 2.7.2.  [from BDE]

*  The definition of SUPPORTS_ONE_ONLY prevents the compiler from trying
   to use "linkonce" sections for a.out.  The definition of
   NO_DBX_FUNCTION_END we had causes it to avoid .stabs symbols that the
   assembler cannot handle for a.out.  [from JDP]

*  The previous "EXCEPTION_SECTION_FUNCTION" is the wrong name for EGCS.
   It also needed tweaking for EGCS.  [from JDP]

Also bump __FreeBSD_cc_version to 400002 in case we need to know we are
using EGCS at some point.

98bf848b69 Add a new predefined preprocessor symbol "__FreeBSD_cc_version",
with a numeric value that describes the feature level of the
compiler.  This can be used to check for the presence/absence of
FreeBSD-specific compiler features.  The value is a decimal number
whose digits have the form VRRRRFF, where:

	V    = Compiler vendor.  0 (elided) means gcc.
	RRRR = Vendor's version number, e.g., 2721 for the current
	       gcc version (2.7.2.1).
	FF   = FreeBSD-specific revision level.  00 means the stock
	       compiler from the vendor.

The value of "__FreeBSD_cc_version" is hard-coded in
"src/contrib/gcc/config/i386/freebsd.h" and must be incremented
when new FreeBSD-specific compiler features are added.  I considered
simply picking up the value of FreeBSD_version from <osreldate.h>.
But that would break cross compiles of gcc.

1de944af88 On i386, freebsd.h and freebsd-elf.h have been merged to combine
aout and elf support. freebsd-elf.h died as a result, so the BINFORMAT
test for elf in src/gnu/usr.bin/cc/cc_tool/Makefile will need to
use freebsd.h, not freebsd-elf.h. That means that alpha will have to

37aebf7ed2 Change the LINK_SPEC to specify the same runtime loader as used on
i386-elf because that is what will be used for FreeBSD/Alpha.

Change the STARTFILE_SPEC to match the non-aout version of i386 so
that the csu files can be built in exactly the same way as i386-elf.
This means that FreeBSD/Alpha departs from NetBSD/Alpha which uses
crt0 and crtbegin/crtend. Since i386-aout uses crt0, I guess it was
decided that i386-elf should use crt1. i386-elf also references
crti and with this change, so does FreeBAS/Alpha.

I think it is important for FreeBSD to have a consistent implementation
across architectures and since ELF is quite compatible (ignoring
differences in 32 and 64 bits), gcc might as well be configured the
same.

Another change is that the entry symbol is _start, not __start as
in NetBSD.

9cb13c2344 First round of changes to support generation of assembler for the old
a.out gas and the binutils gas (elf or a.out) with a single compiler.

This uses other infrastructure not yet committed, in order to support
both a.out and elf it needs to be able to get to both a.out and elf
gas, ld, libs, crt* etc.  So for now, the support is pretty much dormant.

The new freebsd.h file is based on the old freebsd-elf.h file (which has a
long lineage, right back through linux and svr4 files).  The change is
pretty dramatic from a gcc internals standpoint as it overrides a lot of
definitions in order to generate different output based on target mode.
There is potential for screw-ups, so please be on the lookout - gcc's
configuration mechanism wasn't really meant for this kind of thing.
It's believed to compile world etc just fine under both a.out and elf, can
handle global constructors and destructors, handles the differences in
a.out and elf stabs, and what sections things like exceptions go in.

The initial idea came from i386/osfrose.h which is a dual rose/elf format
target.  These two are not as diverse as a.out and elf it would seem.

The cc front-end uses external configuration to determine default object
format (still being thrashed out, so read the source if you want to see
it so far), and has a '-aout' and '-elf' override command line switch.
There are some other internal switches that can be accessed, namely -maout,
-mno-aout, -munderscores and -mnounderscores.  The underscore and local
symbol prefixing rules are controllable seperately to the output format.
(ie: it's possible to generate a.out without the _ prefixes on symbols and
also to generate elf with the _ prefixes.  This isn't quite optimal, but
does seem to work pretty well, except the linkers don't always recognise
the local symbols without their normal names)

The default format is a.out (still), nobody should see any major changes.

With both elf and a.out tools and libraries installed:

[1:26pm]/tmp-223> cc -elf -o hello hello.c
peter@beast[1:27pm]/tmp-224> file hello
hello: ELF 32-bit LSB executable, Intel 80386, version 1 (FreeBSD), dynamically linked, not stripped

[1:27pm]/tmp-227> file hello
hello: FreeBSD/i386 compact demand paged dynamically linked executable not stripped

Since my co-conspirators put a lot of effort into this too, I'll add them

6eb0e3b9f9 Add the necessary defines to the freebsd-elf configuration so that
it can be built via BINFORMAT=elf in the environment.  Most likely
some of the directory defines such as STANDARD_EXEC_PREFIX will
change again soon, as we settle on the proper locations for the
various components.

Note, the build still fails when it tries to compile libgcc2.c
using the ELF compiler, unless arrangements have been made for the
compiler to find the ELF assembler instead of the a.out assembler.

07bb70bf47 Make "gcc -shared" work properly for building shared libraries. An
up-to-date version of c++rt0.o is necessary for this to work right.

Closes PR gnu/3035: gcc -shared flag is broken.

5a55bb419e Disallow "-p" when linking, with a diagnostic that recommends using
"-pg" and gprof(1) instead.  FreeBSD does not support plain "-p" or
prof(1).

Plain "-p" is still allowed when just compiling.  In the compile
phase, "-p" is identical "-pg".  It is used by <bsd.lib.mk> for
building profiled object files.

6a16ae63cd Undo rev 1.4 of freebsd.h and 1.2 freebsd-elf.h, where I added
_BSD4_4 as a predefined symbol.  People on the lists generally didn't care
for it.

dfc33decb2 Add _BSD4_4 as a predefined symbol.
Peter Dufault (dufault@hda.com) suggested this is the most approate symbol
to use.

2.2-R candidate.

2c80f2dbdb Apparently this patch fixes the objc backend on the i386 platforms.
Without this, compiled programs die with FP errors.

This is originally credited to: jlemon@netcom.com (Jonathan Lemon), and
has been forwarded to me by quite a few of people.

87f11ab41b Fix a bug that caused incorrect PIC code to be generated for exceptions.
The symptom was an assembler warning

    "GOT relocation burb: `___EXCEPTION_TABLE__' should be global"

followed (sometimes) by a core dump.  The fix makes the compiler
generate the correct GOTOFF addressing for that symbol, rather than the
GOT addressing it was emitting before.

Warning:  There is still at least one serious bug in the i386 exception
code for PIC.  The exception code that is generated clobbers the GOT
register (%ebx) and then tries to use it later.  That leads to core
dumps at program execution time.  I know where the problem is, but I do
not have a fix for it at this time.  Until it is fixed, exceptions will
not work in PIC code.  This is a general problem for all i386 platforms;
it is not specific to FreeBSD.

a4cd5630b0 Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the
non-i386, non-unix, and generatable files have been trimmed, but can easily
be added in later if needed.

gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's
handy to have both available for reference for such little cost.

The freebsd-specific changes will then be committed, and once the dust has
settled, the bmakefiles will be committed to use this code.
