------- Comment #27 from dominiq at lps dot ens dot fr 2008-02-03 08:41 -------
On i686-apple-darwin9, rev. 132071, gcc.dg/pr35045.c gives an ICE in 32 bit
mode :
/opt/gcc/_gcc_clean/gcc/testsuite/gcc.dg/pr35045.c: In function 'mycacoshf':
/opt/gcc/_gcc_clean/gcc/testsuite/gcc.dg/pr35045.c:26: error: can't find a
register in class 'GENERAL_REGS' while reloading 'asm'
/opt/gcc/_gcc_clean/gcc/testsuite/gcc.dg/pr35045.c:26: error: 'asm' operand has
impossible constraints
The ICE disappears with -m64.
