Raw Normal View History

This is the tcl-scripts which will convert gcc-2.6.0 to bmake form, a patch to gcc from Bruce, and to libg++ by me. I will check in the actual compiler when Jordan has put in the rest of src/gnu.

I have removed the "ljo-Fortran" stuff. It doesn't belong in cc. /phk

Here are the diffs for my port of gcc-2.6.0. FreeBSD-1.1.5 and 4.4lite
have an amazing number of bugs in involving namespace pollution from the
runetype stuff. rune_t should never have been in <stddef.h>. <ctype.h>
does not compile if _ANSI_SOURCE is defined ...
Bruce
Makefile.in:
Rip out debugging stuff from libgcc.a the same as FreeBSD does.
final.c:
o If NO_PROFILE_DATA is defined, don't waste space for unused
profile data.
config/i386/freebsd.h:
o Define specs together near the start.
o For -p and -pg, put -Bstatic in LINK_SPEC instead of in LIB_SPEC
so that it gets seen early enough when other libraries are used.
o Update wchar_t stuff. `wchar_t foo[] = "123";' is broken in
FreeBSD-1.1.5 because wchar_t was changed without changing gcc.
I guess nothing actually uses wchar_t :-).
o FUNCTION_PROFILER: don't waste space and time for unused profile
data and pointer to it. Compatible with FreeBSD-1.x.
o FUNCTION_PROFILER_EPILOGUE: for accurate profiling if there's
a readable clock. Incompatible with FreeBSD-1.x (hide it with
#if 0, or add a dummy mexitcount to the user mcount file and
a real mexitexit to the kernel mcount file). Need a -mflag for
this. Want more profiling stuff (profile before function
prologue...) from osfrose.h.
o Fixed white space in "svr4" stuff. Actually it's osfrose stuff.
Formatting now matches osfrose.h.
config/i386/i386.c:
o Fix bugs: profiling may use the pic register. Need a macro for
this - it is machine-dependent. It is already fixed in osfrose.h
by not using the functions in i386.c.
o Support FUNCTION_PROFILER_EPILOGUE. Avoiding the use of the pic
register is even more complicated for the epilogue than for the
prologue. We don't attempt to. See osfrose.h for the prologue.
config/i386/i386.h:
o Avoid average 1.2% code bloat caused by stupid register allocation.
ginclude/stdarg.h, ginclude/varargs.h:
o Handle Net/2 _VA_LIST_ and 4.4lite _BSD_VA_LIST_ right.
ginclude/stddef.h:
o Handle Net/2 _WCHAR_T_ and 4.4lite _BSD_WCHAR_T_ less wrongly than
before. Copy FreeBSD-1.1.5/4.4lite rune_t brokenness. Remove
extra underscores in _GCC_*_T_ which stopped the Net/2 _PTRDIFF_T_,
_SIZE_T_ and _WCHAR_T_ from being undefined. Still need to
handle the 4.4lite _BSD_PTRDIFF_T_ and _BSD_SIZE_T_. They are too
hard to handle using ifdefs anyway. stddef.h takes 227 lines to
define only 3 ANSI typedefs, 1 bogus typedef and 2 ANSI macros.
