Bug ID: 86548
Summary: GCC could tmp file /tmp/ccDxn2Yd.ltrans0.ltrans.o
could be based on the compiled file name
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jg at jguk dot org
Target Milestone: ---
It's pretty hard to work out which file this o file comes from. Could it
include the first file name in the tmp path to make it clearer where it came
from?
Currently:
/tmp/ccDxn2Yd.ltrans0.ltrans.o
Expected:
/tmp/main.cpp.ccDxn2Yd.ltrans0.ltrans.o
Example below of what I see
