Displaying 1 result from an estimated 1 matches for "src0_neg".

[LLVMdev] Tablegen strings
...t<IL_OP_MOV, (outs GPR:$dst), (ins
GPR:$src0),
"mov $dst, $src0", [(set GPR:$dst, (fneg GPR:$src0))]>;
I want to place a modifier directly after $src0 in the string so that no
space is between the string
and the matched register. I.e. I want to generate "mov $dst, $src0_neg",
however, by putting the
_neg right after $src0 forces it to attempt to match against src0_neg
instead of just src0. Where
can I find the rules for the string pattern matcher so that I can added
arbitrary strings into my
definition.
