Bug #: 14987
Summary: Current gas arm asm syntax checks may be too strict
Product: binutils
Version: 2.24 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gas
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
Current (seen with hjl branch binutils 2.23.51.0.6 to 2.23.51.0.8) arm asm
syntax checks may be a bit too strict.
This is fine:
vld1.32 {d1[]}, [r2], r3
But this whitespace change errors out:
vld1.32 {d1[]}, [r2 ], r3
test.S:6: Error: ']' expected -- `vld1.32 {d1[]},[r2 ],r3'
This causes problems when building x264 (context:
.macro SAD_FUNC w, h, name, align:vararg
vld1.32 {d1[]}, [r2 \align], r3
.endm
called without the align parameter)
The fix on the x264 side is easy, but chances are the behavior seen in older
binutils versions (accepting both versions equally) is preferable.
