Source and preprocessed source plus assembly

This bug does not affect gcc-8. It affects gcc-9 and gcc-10. Using -mlra does not help.

Building with -O1 instead of -O2 helps. I can try to bisect the optimization flag which causes this problem later.

Passing -fno-move-loop-invariants to the command line fixes the problem for me.

Hmm, there is one other source code file within webkit2gtk where -fno-move-loop-invariants does not help. I can only get that particular source file to be compiled if I disable all optimizations.

I tried bisecting the flags between -O0 and -O1 but that didn't work as I expected, unfortunately.

So, I guess we can't compile webkit2gtk until this bug has been fixed :(.

As always, just because the error message seems to be the same, doesn't mean it's the same issue/bug in the compiler.  Please post the other failing code, too.

The second case compiles fine with gcc-8 as well, but fails with g++-9 and g++-10.

The "movsf_ie" insn doesn't allow FP reg -> GP reg moves in its constraints, but it allows it in its predicates "general_movdst_operand" and "general_movsrc_operand".  I will have a look and try to correct it.

I can't reproduce the first case with a standalone sh-elf compiler (GCC 9).

The compile flags mention

      -specs=/usr/share/dpkg/pie-compile.specs

... what's in that specs file?

  (sid-sh4-sbuild)root@sh4-gandi-02:~# cat /usr/share/dpkg/pie-compile.specs 
  *self_spec:
  + %{!r:%{!fpie:%{!fPIE:%{!fpic:%{!fPIC:%{!fno-pic:%{!fno-PIE:%{!no-pie:-fPIE}}}}}}}}

So, since -fPIC is provided on the command line already, it shouldn't be doing anything.

This looks to be an LRA related issue (checking with GCC 10).  Without -mlra it actually compiles fine.  Adding -mlra causes some issues:

Vlad, maybe you have some hint where to look?

Indeed, this seems to be related to LRA.

I just tried to build gcc-9 with LRA enabled by default and the build fails when trying to build gnat with:

checking for shl_load in -ldld... s-gearop.adb: In function 'Ada.Numerics.Complex_Arrays.Back_Substitute.Sub_Row':

            (use (reg:SI 154 fpscr0))

I don't think this is a duplicate. This one is supposed to be without -mlra.

All of the comments here talk about -mlra and even that one all of the comments talk about using -mlra .

I should probably recheck all the issues I reported whether they still affect gcc-13 or trunk. Some of my reports are quite old.
