Changelog

2013-03-18  David Holsgrove <david.holsgrove@xilinx.com>

    * gcc/config/microblaze/microblaze.c: Add
microblaze_asm_output_mi_thunk
      and define TARGET_ASM_OUTPUT_MI_THUNK and

TARGET_ASM_CAN_OUTPUT_MI_THUNK

Sorry it has taken so long to review this patch.

The gcc microblaze-xilinx-elf build with this patch fails here:

+microblaze_asm_output_mi_thunk (FILE *file, tree thunk_fndecl
ATTRIBUTE_UNUSED,
+                               HOST_WIDE_INT delta, HOST_WIDE_INT
vcall_offset,
+                               tree function)
...
+  emit_insn (gen_jump (funexp));

(actually, in output_operand() downstream from this statement) while
compiling
c++98/strstream.cc, with an error that the "%l" operand was not a label.

This is the first occasion when this routine is called.


I had sent a separate patch which should have been applied prior to this
one which
extended the jump insn to accommodate branching without the "%l" print
operand,
but I've since reworked our thunk support to avoid needing this second
patch.

Please find attached updated patch, and new Changelog entry;

2013-07-15  David Holsgrove <david.holsgrove@xilinx.com>

   * gcc/config/microblaze/microblaze.c: Add microblaze_asm_output_mi_thunk
     and define TARGET_ASM_OUTPUT_MI_THUNK and
TARGET_ASM_CAN_OUTPUT_MI_THUNK

I'll post updated patches on the other threads out for review now.

thanks,
David



Committed revision 201185.


Thanks Michael.

I think the content of your commit doesnt line up with this Changelog
entry or mail though,

http://gcc.gnu.org/git/?p=gcc.git;a=commit;h=c4fcbf4cd03c11aa1bc707b00dd95ba52f963b39

It looks like the atomic builtin patch which was posted as this mail;
http://gcc.gnu.org/ml/gcc-patches/2013-07/msg00551.html

Yes, I picked up the wrong ChangeLog and email.  I fixed the ChangeLog.
