2005-05-04* Correct the function prototypes for some of the functions to match theReid Spencer
actual spec (int -> uint) * Add the ability to get/cache the strlen function prototype. * Make sure generated values are appropriately named for debugging purposes * Add the SPrintFOptimiation for 4 casts of sprintf optimization: sprintf(str,cstr) -> llvm.memcpy(str,cstr) (if cstr has no %) sprintf(str,"") -> store sbyte 0, str sprintf(str,"%s",src) -> llvm.memcpy(str,src) (if src is constant) sprintf(str,"%c",chr) -> store chr, str ; store sbyte 0, str+1 The sprintf optimization didn't fire as much as I had hoped: 2 MultiSource/Applications/SPASS 5 MultiSource/Benchmarks/McCat/18-imp 22 MultiSource/Benchmarks/Prolangs-C/TimberWolfMC 1 MultiSource/Benchmarks/Prolangs-C/assembler 6 MultiSource/Benchmarks/Prolangs-C/unix-smail 2 MultiSource/Benchmarks/mediabench/mpeg2/mpeg2dec git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21679 91177308-0d34-0410-b5e6-96231b3b80d8
