Bug ID: 97989
Summary: -g3 somehow breaks -E
Product: gcc
Version: 10.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: stsp at users dot sourceforge.net
Target Milestone: ---
$ gcc -E -Wp,-P -xc - </dev/null
No output, correct.
$ gcc -g3 -E -Wp,-P -xc - </dev/null
Lots of cpp defines in output, incorrect.
$ clang -g3 -E -Wp,-P -xc - </dev/null
No output, correct.
AFAIK no "#define"s should be outputted by the
cpp pass. Quite the opposite, cpp should expand
them all. But with -g3 for some reason this doesn't
happen.
