[Bug bootstrap/21556] New: [4.1 Regression] ia64-hpux bootstrap fails

The patch

2005-05-11  Richard Henderson  <rth@redhat.com>

        PR target/21412
        * config/ia64/ia64.c (TARGET_CANNOT_FORCE_CONST_MEM): New.
        (ia64_cannot_force_const_mem): New.
        [...]

causes mainline bootstrap to fail on ia64-hpux.  The failure is when building
libgcc with the stage2 compiler, i.e. in what follows ./xgcc is the stage2
compiler built with the stage1 compiler so it seems the stage1 compiler is
miscompiling the stage2 compiler.

Well, since it works on ia64-linux, you'll have to give me more information.
I assume I'm failing to addp4 in the right place, or something...

[Bug bootstrap/21556] [4.0/4.1 Regression] ia64-hpux bootstrap fails on mainline, TLS failures on 4.0 branch

[jsm28 at gcc dot gnu dot org]

------- Additional Comments From jsm28 at gcc dot gnu dot org  2005-05-14 20:53 -------
I'm now running the C testsuite with the before-and-after stage1 compilers to
see if that shows up any problems.

On 4.0 branch the patch doesn't cause bootstrap failure but there are a number
of new testsuite failures, all -milp32 only, which might show up with a
cross-compiler and indicate the source of this or a related problem.  All these
appeared between 20050512 and 20050514, and seem likely to be related to this patch.

(Also note that gcc.dg/tls/opt-9.c still fails for -milp32 although it now
passes for -mlp64.)

C testsuite failures with the stage1 compiler introduced by this patch on
mainline are the same as the new failures on 4.0 branch.
