Bug #: 11855
Summary: ARM: inline asm does not support pre-UAL conditional
LDRH etc
Product: libraries
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: ARM
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
The inline asm parser should accept the old forms of conditional LDRH and
friends, e.g. LDREQH should be an alias for LDRHEQ. GCC supports _only_
these forms in ARM mode, so this is essential for compatibility.
Test case:
void foo(void)
{
__asm__ ("ldreqh r0, [r1]");
}
Fails like this:
asm.c:3:14: error: invalid instruction
__asm__ ("ldreqh r0, [r1]");
^
<inline asm>:1:2: note: instantiated into assembly here
ldreqh r0, [r1]
^
1 error generated.
