21 GCC HEAD regressions, 14 new, with your patch on 2004-05-14T06:33:11Z.

[Andrew Pinski]

Some analysis of the problems of the new failures:

Known gcov problems (no CFG at -O0):
> native g++.sum g++.dg/gcov/gcov-1.C
> native g++.sum g++.dg/gcov/gcov-2.C
> native gcc.sum gcc.misc-tests/gcov-4b.c


No warnings for no return statements (need CFG at -O0, there is a PR  
for it):
> native g++.sum g++.old-deja/g++.brendan/crash13.C
> native g++.sum g++.old-deja/g++.bugs/900205_03.C
> native g++.sum g++.old-deja/g++.law/friend5.C
> native g++.sum g++.old-deja/g++.mike/p646.C


Labels after the return are being removed even though they are  
referenced
(there is a PR for this):
> native gcc.sum gcc.c-torture/compile/20021108-1.c
> native gcc.sum gcc.c-torture/compile/labels-1.c
> native gcc.sum gcc.c-torture/compile/labels-2.c

/Users/pinskia/src/gcc-checkin/src/gcc/testsuite/gcc.dg/altivec- 
varargs-1.c:22: warning: second parameter of `va_start' not last named  
argument:

The issue I think here is that the vector is being copied into a
temp before it is passed to va_start and it is a generic bug which
should be filed and fixed.
> native gcc.sum gcc.dg/altivec-varargs-1.c


I do not get this failure on my system at all as it is just a timeout:
> native gcc.sum gcc.dg/c99-intconst-1.c


The following two are due to that the constant Objective-C strings
not being the same I do not know how to fix this bug at all, I think
it is a bug in the Objective-C front-end not caching the constructors:
> native objc.sum objc.dg/const-str-3.m
> native objc.sum objc.dg/const-str-4.m
