Bug ID: 25203
Summary: [aarch64] invalid operand for instruction on SIMD
instructions
Product: clang
Version: 3.7
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: riku.voi...@linaro.org
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
-cut-
#include <stdio.h>
int main(void)
{
asm("fmul v22.2s,v6.2s,v0.s[0]");
asm("fmul v22.2s,v6.2s,v0.2s[0]");
return 0;
}
-cut-
GCC is happy to assemble both forms of the instruction, but clang throws an
error on the second:
$ clang hello.c -o hello
<inline asm>:1:25: error: invalid operand for instruction
fmul v22.2s,v6.2s,v0.2s[0]
^
1 error generated.
It seems the parser is a bit too strict here.
