Bug ID: 22912
Summary: .irp variable not expanding if followed by a parameter
defined earlier
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: andre.simoesdiasvieira at arm dot com
Target Milestone: ---
With the following input:
.macro mname op0, op1
.irp p0, _and_, _or_
\op0\p0\op1
.endr
.endm
.syntax unified
.text
mname banana, pear
I would expect the macro to expand to:
banana_and_pear
banana_or_pear
Unfortunately when passing it to arm-none-eabi-as I get:
Error: bad instruction `banana\p0pear'
Error: bad instruction `banana\p0pear'
I have also tried this with \() in between operands, but no luck. FYI, if I
change this to:
.macro mname op0
.irp op1, pear
.irp p0, _and_, _or_
\op0\p0\op1
.endr
.endr
.endm
It still will not work, however, if I move the op1 irp past the p0 irp:
.macro mname op0
.irp p0, _and_, _or_
.irp op1, pear
\op0\p0\op1
.endr
.endr
.endm
then I get the expected:
banana_and_pear
banana_or_pear
