This weak I investigated GCC trunk fails to compile test 186.crafty
from SPECINT2000
on ARM. File validate.c compilation leads to this:
/tmp/ccXFsLlG.s: Assembler messages:
/tmp/ccXFsLlG.s:3411: Error: bad immediate value for offset (4112)
/tmp/ccXFsLlG.s:7069: Error: bad immediate value for offset (4096)
I find a patch, which causes the problem.
http://gcc.gnu.org/ml/gcc-patches/2011-08/msg01249.html
Ramana, you forgot to set count = 2 in one case.
This patch fixes the problem successfully.
Cross-compiler regtest showed no new failures. All SPECINT2000 tests
work correctly.
Ok for trunk?
