Bug #: 13803
Summary: llvm-mc treats .n suffix as .w suffix for ADC
Product: libraries
Version: trunk
Platform: PC
OS/Version: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: ARM
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Fails:
echo "adc.w r0, r1, #1" | llvm-mc -triple=thumbv7 -show-encoding
Also fails for 'sbc.w' and its variants.
Workaround:
echo "adc r0, r1, #1" | llvm-mc -triple=thumbv7 -show-encoding
Awkward workaround, use ".n", but it is still encoded with 32-bits:
echo "adc.n r0, r1, #1" | llvm-mc -triple=thumbv7 -show-encoding
