Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org

The following code demonstrates what might be a parser bug, this is armv7
assembly (and happened in real NetBSD code):
#define AWIN_SRAM_VER_R_EN (1<<15)
# this works
# it's bit 15
orr r1, r1, #(AWIN_SRAM_VER_R_EN << 8)
# this fails
orr r1, r1, #(AWIN_SRAM_VER_R_EN << 8) # it's bit 15
Save as test.S, invoke gcc like:
> armv7--netbsdelf-eabihf-gcc -c test.S
test.S: Assembler messages:
test.S:9: Error: garbage following instruction -- `orr
r1,r1,#((1<<15)<<8)#it115bit 15'
