I can confirm this works on the gcc-13 branch, for both c++17 and c++20 - feel
free to close this issue.

If you go back a bit further, is there a speculative load of one of those
registers
(probably r47 / r59 ) ?
A speculative load will have a .s I think.
I believe ILL_REGNAT should actually be a SEGV, not SI

Looks good, that's a lot of gcc versions!
For clarification, I assume this is using the HP aCC compiler for binutils
etc., rather than the bundled /usr/ccs/bin cc ?

I tried a gcc 11 build with patched 2.30 binutils and it worked.
I also tried building binutils 2.36 with just /opt/aCC/bin and no gcc.
I didn't get any gnu99 errors, but it did fail because plugin-api.h c

Yeah, it sure eats up the space.
One question about PR66319 - it's marked as resolved, so is this committed as a
patch in the trunk ?

--- Comment #238 from John Buddery ---
Thanks, I'll give it a go.
It seems binutils 2.32 and earlier works fine in 32 bit mode, but 2.33.1 and
later require a 64 bit build for 64 bit objects to work reliably.
Was your 11.1 build successful ?

--- Comment #235 from John Buddery ---
Interesting - that's with a 32 bit gas ?
It does look like you have got past the point in stage1 where ld was crashing.
It could be a change between 2.30 and 2.36 I guess, I might see if I can narrow
it dow

--- Comment #233 from John Buddery ---
One additional note - when building the patched binutils 2.36, it must be built
as 64 bit executables.
It seems that a 32 bit gas does not produce 64 bit object files properly on
this platform, causing the

The #undef MAKE_DECL_ONE_ONLY is only for older builds, it's not needed with
the gcc 11 patches.
It was an alternative single line fix which works for 4.7.2 and 4.9.4, which
you need to build if you're star

The mpfr issue seems to be an issue with gcc 4.9.2 compiling later mpfr
versions.
It builds with 4.7.2, so as a workaround try building mpfr outside the gcc tree
using 4.7.2. This may mean you need to build

Sorry it took a while, I've been away for a bit and have lots to catch up on.
These patches are for 11.1.0, but should work on earlier versions too. With

--- Comment #225 from John Buddery ---
Yes, I looked briefly at that - I added a new class, but then started hitting
bundling errors because it wasn't being positioned correctly in the 3
instruction bundle.
It will need more changes to itanium2.

Thanks - that is neater, as it avoids the need to change the calls in ia64.c,
which gets messy.
The simplest variant I have is:

Great, thanks - I'll look at ia64.c and build and test with that change.
Yes, "b" on ia64 seems to be a branch register, and the brl op only accepts
immediate values not registers. Initially I hoped the ass

Thanks very much for adding the binutils patch.
Sorry, I'm new to .md definitions, so I've probably got this wrong. Did you
mean something like:

Thanks for the quick fix - this resolves the ICE in 8.0 for me, and applying to
7.2 fixes the invalid code generation I was seeing there.

You can use --disable-libgomp in the configure command, I had to do this on my

My ld is slightly older:

It may have been older still when I built gcc, as OS patches have been applied
since then.

I did get a working 4.9.2 build, with the workaround from my earlier comment.
It's a 32 bit build, bootstrapped with the hp 4.6.2 gcc distribution, my config
line was:

I should clarify that the workaround above only works fully on 4.9.2 and
earlier.
