35d4aa10d7 Unbreak amd64<->i386 cross builds. 2010-12-02 17:36:47 +00:00

5a7bfc90a9 The driver-XXX.c files used for host CPU detection with -march=native
should not be compiled in the cross-tools case (where -march=native makes
no sense). This fixes cross-building x86 toolchains on non-x86 systems.

7f08176ee8 Add the ability for GDB to printout the thread name along with other
thread specific informations.

In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
- For cores, a new ELF note is added (NT_THRMISC) that can be used for
  storing thread specific, miscellaneous, informations. Right now it is
  just popluated with a thread name.

GDB, then, retrieves the correct informations from the corefile via the
BFD interface, as it groks the ELF notes and create appropriate
pseudo-sections.

I've had a report of a sparc64 system where cc1 generates illegal

hosing all sparc64 boxes out there, fall back to libgcc to prevent more

39cd938c39 Replace libgcc.a by libcompiler_rt.a.
libcompiler_rt.a is a BSD licensed C language runtime, which implements
many routines which are linked into binaries on architectures where
certain functionality is missing (e.g. 64 bits mul/div on i386).

Unfortunately, libcompiler_rt cannot replace libgcc entirely. Certain
features, such as an unwinder for exception handling, are missing.
That's why only libgcc.a is replaced for now, because this one does seem
to be complete.

Tested by:	rene (amd64), nwhitehorn (powerpc), droso (i386 exprun)
		and many others. Thanks!

b70519663c Don't use ${LIB} to obtain the library name.
Once we use libcompiler_rt, the LIB-line must go, to prevent libgcc.a
from being built. Therefore, just hardcode the name.

e8dce5b9b3 Complete the integration of tbemd branch into head.
TARGET_BIG_ENDIAN is now completely dead, except where it was
originally supposed to be used (internally in the toolchain building).

TARGET_ARCH has changed in three cases:
(1) Little endian mips has changed to mipsel.
(2) Big endian mips has changed to mipseb.
(3) Big endian arm has changed to armeb.

Some additional changes are needed to make 'make universe' work on arm
and mips after this change, so those are commented out for now.

UPDATING information will be forthcoming.  Any remaining rough edges
will be hammered out in -current.

d205253515 When building world with clang, for gnu/lib/libobjc, sys/boot/i386/boot2
and sys/boot/pc98/boot2, do not simply assign 'gcc' to CC, since compile
flags are sometimes passed via this variable, for example during the
build32 stage on amd64.  This caused the 32-bit libobjc build on amd64
to fail.

Instead, only replace the first instance of clang (if any, including
optional path) with gcc, and leave the arguments alone.

2751839107 GCC defines built-ins for atomic instructions found on i486 and higher.
Because FreeBSD no longer supports the 80386 cpu all code targeting
FreeBSD/i386 necessarily runs on i486 or higher so the compiler
built-ins can be used by default inside libstdc++ and in C++ headers.
This allows newly compiled C++ code to inline some atomic operations.
Old binaries continue to use libstdc++ functions.

b57429d082 Create a checklist and call one of the *printw() functions from the
selected() callback. When the dialog first appears, you will not see
the printed statement on the dialog, if you move down one, you will,
move up again and it now appears. I am assuming that you call a
*printw() function on a line in the dialog box of course.

The fix, from the pr:
	This is a hack at best, I looked at the redraw code in
	dialog_checklist() and took the minimal amount of it out to do
	a simple "refresh" right after the items are drawn. This
	doesn't hurt anything and makes the library work like it
	should. There is probably a better way however =).

7996bf419b kgdb: correctly map sections to addresses in elf object modules (amd64)
Unlike for modules with dso type, in elf object modules all the sections
have virtual address of zero.  So, it is insufficient to add module base
address to section virtual address (as recorded in section header) to
get section address in kernel memory.
Instead, we should apply the same calculations that are performed by
kernel loaders (in boot code and in kernel) when they lay out sections
in memory.

15744a9c4c Often reported issue with newer ld is:
error in /usr/lib/crtendS.o(.eh_frame); no .eh_frame_hdr table will be created.

The issue is that crtend is compiled with unwind table, and also it
places the special CIE into the .eh_frame indicating the end of section,
that is located before generated unwind table. New ld has assertion that
verifies that closing CIE is indeed the last CIE, causing the crypting
message to be issued, and refusing to generate dwarf unwind.

Add -fno-asynchronous-unwind-tables to disable unwind table generation
for crtbegin/crtend. While there, disable omitting the frame pointer [1].
