I am using LLVM 2.8 on Ubuntu 10.10. (new to both) I change name of instruction on XXXInstrInfo.td ( Sparc, X86 and XCore). I looked into XXXGenAsmWriter.inc and I have seen the new instruction name. But when I run llc for the three targets it prints out the old instruction name. For example for XCore I change “divs” to “sdiv” like >From => def DIVS_l3r :

...nstruction > let say "divs" to "newdivs", > > like > def DIVS_l3r : FL3R<"newdivs", sdiv>; > > When I run llc with option -march=xcore, after I make the modification, it > still outputs "divs", not "newdivs". I looked into XCoreGenAsmWriter.inc, > and made sure that string AsmStrs includes "newdivs". I don't know if the tablegen gets rebuilt when you re-compile llvm, but it could also be that you are changing the wrong rule... I'll leave the tablegen experts answer that... ;) cheers, --renato

...nge the name of one of the instruction let say "divs" to "newdivs", like def DIVS_l3r : FL3R<"newdivs", sdiv>; When I run llc with option -march=xcore, after I make the modification, it still outputs "divs", not "newdivs". I looked into XCoreGenAsmWriter.inc, and made sure that string AsmStrs includes "newdivs". If this is linkage problem how can I solve it? -------------- next part -------------- An HTML attachment was scrubbed...
