kristerw 46e954b5e5 C++ exceptions doesn't work in i386 shared libs when using sjlj exceptions 
(as a.out does per default.)  This is because the compiler forgets to
restore the PIC register after a builtin_setjmp (i.e. when catching an
exception.)  This fix is taken from the gcc 2.95 branch.

Fixes PR#9110.

thorpej 4a9e81df67 Pass in the appropriate machine directive to the assembler if an -mcpu=... 
option is given to the compiler.  It's silly to have to specify it twice
on a command line (e.g. -mcpu=ev56 -Wa,-mev56), especially considering
that if you don't, and the compiler emits e.g. a BWX instruction, the
assembler will treat it as a macro, open-coding an equivalent, which can
have some serious unwanted side-effects in some situations.

Also, don't treat e.g. 21164 and ev5 as equivalent; the assembler treats
them differently: 21164 enables PALcode-only instructions, while ev5
does not.

drochner 16dcb3a8fd more radical fix for the last problem, from the egcs/gcc mailing list 
(http://egcs.cygnus.com/ml/gcc/1999-10/msg00400.html).
Log message:
          * combine.c (get_last_value): If the last set of a register
        is after subst_low_cuid, then we can not use it to determine
        the register's last value.

kleink 0b9965d236 For ELF, rename the profiling entry from mcount to __mcount to avoid clashing 
with the user's namespace, also within file scope; for binary compatibility,
define a weak alias for the previous name to cover our tracks.

drochner cfab800438 Fix for a misoptimization, from the egcs/gcc mailing list

        known set is somewhere in between the insns being combined.

offsets to the beginning of the function. Other i386 ELF systems do
this as well, and gdb expects it by default.

jonathan 1192ce7d8f Patch FUNCTION_PROFILER to avoid code-scheduling botch when compiling 
with -mabicalls: the gcc/egcs code emits hand-scheduled code with an
insn in a "jal _mcount" delayslot. But with -mabicalls, the "jal"
expands into a call via $t9 and the delay-slot is already filled.

See PR#5248.
