Bug ID: 114160
Summary: ICE in dwarf2out_frame_debug_cfa_offset RISCV
thead-c906
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: nop at unearthly dot dev
Target Milestone: ---
Created attachment 57573
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57573&action=edit
cvise produced reproduction case
Taking out -O2, -mcpu, or -fPIC out resolves the issue. Additionally, this
doesn't happen on -mtune=thead-c906
This does not happen on gcc 14
mu-loong ~ # gcc -v -O2 -mcpu=thead-c906 -fPIC GBZ.c
Using built-in specs.
