Bug ID: 107482
Summary: out-of-bounds heap access in IRA
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: jcmvbkbc at gcc dot gnu.org
Target Milestone: ---
Created attachment 53806
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53806&action=edit
_gcov.i
Inside the functions update_costs_from_allocno and
assign_hard_reg the macro ALLOCNO_COLOR_DATA
may be applied to objects of type 'struct ira_allocno' whose
add_data field wasn't changed in the function color_pass to
point to a memory area sized for struct allocno_color_data.
It triggers ASAN and can be reproduced without ASAN with the attached
patch on a compiler built from revision gcc-13-3563-gf36bba013361
for target=microblazeel-linux-gnu:
$ gcc/cc1 -O2 _gcov.i
../../../../gcc/libgcc/libgcov-driver.c: In function ‘gcov_do_dump.constprop’:
../../../../gcc/libgcc/libgcov-driver.c:704:1: internal compiler error: in
assign_hard_reg, at ira-color.cc:2006

It can also be reproduced with the same input file and command line by the
compiler built from the same revision for target=xtensa-linux-uclibc.
