Subject: [PATCH 148/188] LoongArch: Remove unused and incorrect
|
||
|
|
"sge<u>_<X:mode><GPR:mode>" define_insn
|
||
|
|
|
||
|
|
If this insn is really used, we'll have something like
|
||
|
|
|
||
|
|
slti $r4,$r0,$r5
|
||
|
|
|
||
|
|
in the code. The assembler will reject it because slti wants 2
|
||
|
|
register operands and 1 immediate operand. But we've not got any bug
|
||
|
|
report for this, indicating this define_insn is unused at all.
|
||
|
|
|
||
|
|
Note that do_store_flag (in expr.cc) is already converting x >= 1 to
|
||
|
|
x > 0 unconditionally, so this define_insn is indeed unused and we can
|
||
|
|
just remove it.

(sge<u>_<X:mode><GPR:mode>): Remove.
