             Bug #: 56732
           Summary: ICE
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: diffgeom@gmail.com

Preprocessed source code

I was trying to compile Ndless with GCC 4.8.0 (configured to cross-compile to
arm-none-eabi), and it fails on this file. This compiled in GCC 4.7.2. It seems
that it compiles only if I remove the optimization flag or change it to -O1,
but not with -O2, -O3, or -Os.

The command line used to compile it is:
"/usr/local/bin/arm-none-eabi-gcc" -mcpu=arm7tdmi -I
"/home/rajiv/.ndless/include" -I
"/home/rajiv/ndless/ndless/Ndless-SDK/ndless/bin/../include" -I
"/home/rajiv/ndless/ndless/Ndless-SDK/ndless/bin/../3rd/nSDL/include" -I
"/home/rajiv/ndless/ndless/Ndless-SDK/ndless/bin/../3rd/nspireio/include" -fpic
-fno-builtin -D _TINSPIRE -Os -nostdlib -Wall -W -Wno-strict-aliasing -c
ploaderhook.c

The error occurs at function plh_hook:

ploaderhook.c: In function ‘plh_hook’:
ploaderhook.c:156:1: internal compiler error: in advance_target_bb, at

--- Comment #1 from Manuel López-Ibáñez <manu at gcc dot gnu.org> 2013-03-25 22:55:48 UTC ---
This is because the second error is not an error but a note clarifying with
first error. In g++, some notes are "indented" because the output is such a
mess it is hard to find out stuff. The fix is to replace the second permerror
by inform like: (totally untested)

Although it doesn't show up here, I've also backported the fix to the 4.7
branch and committed it as rev. 197071.

OK to close this PR?
