- Subject: Fix gcc.dg/shrink-wrap-alloca.c
The new gcc.dg/shrink-wrap-alloca.c FAILs on 64-bit Solaris 10/x86:
Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/shrink-wrap-alloca.c:4:14: warning: conflicting types for built-in function 'alloca' [enabled by default]
The following patch fixes it by using __builtin_alloca, as pre-approved
by Jeff.
Tested with the appropriate runtest invocation on i386-pc-solaris2.10
and x86_64-unknown-linux-gnu, installed on mainline.
