Bug ID: 95343
Summary: IPA-SRA can result in bad debug info about removed
function arguments
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: jamborm at gcc dot gnu.org
Target Milestone: ---

Testcase
ipa_param_adjustments::modify_call does not properly account for extra
arguments left over from clone materialization when recording debug
info. Therefore, when the attached testcase is compiled with -O2 or
higher and run in gdb with a breakpoint is set at line 20 where we
examine the value of parameter i, it incorrectly reports 4, even
though it should be 2.
