Bug ID: 60264
Summary: ARM ICE in dwarf2out_frame_debug_adjust_cfa, at
dwarf2cfi.c:1090
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: chrbr at gcc dot gnu.org
Created attachment 32164
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32164&action=edit
testcase
compiling the attached case with
-O2 -mapcs -mfloat-abi=hard
we have the epilogue
fldmfdd ip!, {d8} @ 31 *vfp_pop_multiple_with_writeback [length
= 4] frame_related_p
sub sp, fp, #12 @ 33 *arm_addsi3/12 [length = 4]
ldmia sp, {fp, sp, lr} @ 34 *ldm3_ia [length = 4]
frame_related_p
Notice fldmfdd sets the cfa reg to IP, and the ldmia expects SP. This crashes
with -g on this assertion.
