[Bug lto/41564] New: -fdump-tree-all does not work with lto

I was testing out LTO and found -fdump-tree-all did not work.

I even made sure that -fdump-tree-all was added to the command line:
/home/pinskia/lto-gcc/libexec/gcc/x86_64-unknown-linux-gnu/4.5.0/lto1 -quiet
-dumpbase lua.o -mtune=generic -auxbase-strip /tmp/ccMdUKXU.lto.o -O2 -Wall
-version -fdump-tree-all @t.sh

And it still does not work.

           Summary: -fdump-tree-all does not work with lto
           Product: gcc
           Version: 4.5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

It works - look into /tmp.

$ ./xgcc -B. -o t t.i -flto -fdump-tree-all
$ ls /tmp/
ccJKyW5f.o.140t.optimized
ccJKyW5f.o.221t.statistics

you need to use -save-temps to get nice names here.  It also works with your
lto1 invocation which would dump in /tmp/lua.o.

So, is your complaint that it dumps to /tmp or that it dumps with a cc*.o
base if not using -save-temps?

Ok, this works but /tmp seems the wrong place for the dumps.


pinskia@gcc13:~/src/lua-5.1.4/src$ !ls
ls /tmp/*.[0-9][0-9][0-9]t.*
/tmp/lua.o.057t.addressables

One symptom is that (from PR41708) the dg-torture leaves behind dump files
in /tmp:

[hjl@gnu-26 tmp]$ ls cc*
cc04uxjw.o.063t.alias      ccij5SzB.o.063t.alias      ccS3qzsd.o.063t.alias
cc2agDxi.o.063t.alias      ccIPR8Wx.o.063t.alias      ccsaxP8c.wpa.o.063t.alias
cc2P8Is7.o.063t.alias      cck79Seb.wpa.o.063t.alias  ccsLaryV.wpa.o.063t.alias

My /tmp is small so this causes it to be filled up quickly.  Is there a simple
work around?

Actually thinking about it, setting TMPDIR env is a workaround :)

Since LTO tree dump is quite different, can't we give it a different
command line option, something like -fdump-tree-lto-all, instead of
enabling it with -fdump-tree-all?
