[LLVMdev] need help on llc option -march=?

[Atse Zeriakob]

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 in XCoreInstrInfo.td I change 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?
