[LLVMdev] [MC] Removing relaxation control
Hi all,
clang -O0 currently differs from -O1 and higher in passing down
-mrelax-all. When compiling assembler files, this results in conditional
jumps using the relaxed forms, which is surprising. Based on the
discussion on IRC, I did a llvm/clang release build with -O0 for
OPTIMIZER and -O0 -mno-relax-all.
Result is:
-O0 (-mrelax-all) 68m27.893s 254m19.920s 1m45.720s
-O0 -mno-relax-all
