Bug ID: 82806
Summary: Stabilize paths in assembler and dumps
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Recently I've run into the following issues:
1. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82415 "Bug 82415 - FAIL:
gcc.target/i386/naked-1.c scan-assembler-not ret".
I build and tested gcc in a directory with "ret" in the path, and an assembler
scan triggered on that.
2. https://gcc.gnu.org/ml/gcc-patches/2017-11/msg00055.html.
I build and tested gcc in a directory with "while" in the path, and a tree-dump
scan triggered on that.
I wonder if we can add a gcc option -fstrip-path[=<string>] that strips (or
replaces with a constant string) paths in compiler output such as dumps and
assembler.
By using by default fstrip-path="stripped-path" or some such in the testsuite,
we can stabilize compiler output and reduce noise in the testsuite.

3. https://gcc.gnu.org/ml/gcc-patches/2018-03/msg01357.html
vrp104.c scan-tree-dump-times "switch"
I build and tested gcc in a directory with switch in the path, and an tree-dump
scan triggered on that.
