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
Created attachment 29723
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29723
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 âplh_hookâ:
ploaderhook.c:156:1: internal compiler error: in advance_target_bb, at

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?

Started with http://gcc.gnu.org/r188742 or http://gcc.gnu.org/r188743.
With r188742 I get:

Thanks for the small testcase! There is indeed a problem with rtl epilogue
generated for naked functions. Here is a fix, testing in progress.
