Bug ID: 123519
Summary: a681: internal compiler error: Segmentation fault
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: algol68
Assignee: algol68 at gcc dot gnu.org
Reporter: mnabipoor at gnu dot org
Target Milestone: ---
Hi.
I was working on my patch which adds `--disable-algol68-posix-prelude' option
to make it possible to build for baremetal systems. I rebased it recently on
master (1f7e64d56bce2c51bbc093a3dfb1778eaddf12ee) and tried to build it with
the following options:
$GCC/configure --disable-algol68-posix-prelude --target=arm-none-eabi
--prefix=$PREFIX --disable-shared --disable-threads --disable-tls --disable-nls
--with-system-zlib --with-newlib --enable-multilib
--with-multilib-list=rmprofile --disable-libmudflap --disable-libssp
--disable-libquadmath --disable-libgomp --disable-werror CFLAGS_FOR_TARGET=-Os
CXXFLAGS_FOR_TARGET=-Os --enable-languages=c,algol68,c++,lto
It's a multilib build for R/M profiles (--with-multilib-list=rmprofile).
It managed to successfully build the libga68 in the following directories:
- arm-none-eabi/arm/v5te/softfp/libga68
- arm-none-eabi/arm/v5te/hard/libga68
And failed in `arm-none-eabi/thumb/nofp/libga68' with an ICE:
(I changed the output to remove names of actual prefix directory and replaced
them with $PREFIX)
