Hi Michael,
I've attached the same patch based on latest gcc master.
Can this be applied to gcc-4_8-branch also.
thanks,
David

Add SImode to cstoresf4's comparison operator, prevents ICE during combine
rtl pass with error message;
internal compiler error: in simplify_subreg, at simplify-rtx.c:5725
Use ordered_comparison_operator predicate to limit operators to
those fcmp can handle, and letting compiler reorder insns to
accommodate unordered as necessary.
Changelog entry;

* gcc/config/microblaze/microblaze.md: Fix cstoresf4 and cbranchsf4
Can this be backported to gcc-4_8-branch also?
Hi David --
You mention that this patch fixes an ICE. Is there a failing test
case in the GCC Test Suite? Is there a GCC PR for this ICE?
If not, please add a test case to the patch.
Hi Michael,
Thanks for the reply. No, unfortunately there isn’t an existing test case which
shows this ICE.
I'm in the process of trying to recreate and distil into a small test case if
possible, but the error was encountered whilst building a rather large app
using microblaze linux.
I've attached updated patch which includes a test case to check for
this ICE. Tested on microblaze baremetal and microblazeel linux
toolchains with / without my change.
Updated ChangeLogs would be;
gcc/ChangeLog
2014-01-22 David Holsgrove <david.holsgr...@xilinx.com>
* config/microblaze/microblaze.md(cstoresf4, cbranchsf4): Replace
comparison_operator with ordered_comparison_operator.
testsuite/ChangeLog
2014-01-22 David holsgrove <david.holsgr...@xilinx.com>
* testsuite/gcc.target/microblaze/isa/fcmp4.c: New file.
thanks,
David
