They differ because the parm was copied in split_complex_args. Removing the test at var-tracking.c:2389 and using the decl would not work because some REGs in the insn chain contain the original parm and some contain the copied parm and thus these variables would not match resulting in wrong debug info. My patch not to copy parms of other types than complex types however broke bootstrap, I'll look into it later today. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14058 ^ permalink raw reply [flat|nested] 7+ messages in thread
