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? 2012-02-10 Roman Zhuykov <zhr...@ispras.ru> * config/arm/arm.c (output_move_double): In one case properly count number of instructions that will be emitted. --- gcc/config/arm/arm.c | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-) diff --git a/gcc/config/arm/arm.c b/gcc/config/arm/arm.c index e2ab102..7f0dc6b 100644 --- a/gcc/config/arm/arm.c +++ b/gcc/config/arm/arm.c @@ -14205,6 +14205,9 @@ output_move_double (rtx *operands, bool emit, int *count) output_asm_insn ("sub%?\t%0, %1, %2", otherops); } + if (count) + *count = 2; + if (TARGET_LDRD) return "ldr%(d%)\t%0, [%1]"; -- Roman Zhuykov zhr...@ispras.ru
