[Bug lto/44143] [4.6 Regression] -fdump-tree-all for lto does not work as expected

[rguenth at gcc dot gnu dot org]

------- Comment #1 from rguenth at gcc dot gnu dot org  2010-05-14 16:26 -------
Did it?

> ./xgcc -B. -o t 1.c 2.c -flto -fdump-tree-optimized
> ls t.142t.optimized 1.c.142t.optimized 2.c.142t.optimized 
1.c.142t.optimized  2.c.142t.optimized  t.142t.optimized

or do you mean with -fwhopr?  Yes, there it might have been - but I'd like
to change 4.5 behavior there anyway.

------- Comment #3 from rguenth at gcc dot gnu dot org  2010-05-14 16:33 -------
So that's not "-fdump-tree-* do not work as expected" but "testing leaves
temporary files behind"?

------- Comment #6 from rguenth at gcc dot gnu dot org  2010-05-14 17:13 -------
Btw, I like to have wpa/ltrans dumps named after the final output file, not
random source files.  That would allow easier adaption of dg-scan-* i think.

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=159536
Log:
2010-05-18  Richard Guenther  <rguenther@suse.de>

        PR lto/44143
        * lto-wrapper.c (verbose): New variable.  Initialize from -v.
        (debug): Initialize from -save-temps.
        (collect_execute): Print command-line when verbose.
        (run_gcc): Always use COLLECT_GCC_OPTIONS.  Use fork_execute
        for ltrans invocation.  Produce -dumpbase flag again.
        (process_args): Remove.
        (main): Simplify.
        * collect2.c (maybe_run_lto_and_relink): Only pass object
        files to lto-wrapper.
        * gcc.c (LINK_COMMAND_SPEC): Likewise.
