libgomp testsuite fails with a segfault. It segfaults in
gomp_resolve_num_threads(), accessing the second TLS value.
The first access:
.LBB28:
.file 2 "../../../src/libgomp/libgomp.h"
.loc 2 380 0
bcl 20,31,$+8
.long _GLOBAL_OFFSET_TABLE_-$
mflr 9
lwz 0,0(9)
add 9,9,0
lwz 9,gomp_tls_data@got@tprel(9)
add 9,9,gomp_tls_data@tls
lwz 9,40(9)
The second:
.LBE27:
.loc 1 47 0
cmpwi 7,3,1
beq- 7,.L37
.LVL32:
.loc 1 49 0
bcl 20,31,$+8
.long _GLOBAL_OFFSET_TABLE_-$
mflr 9
add 9,9,0
lwz 9,gomp_tls_data@got@tprel(9)
add 9,9,gomp_tls_data@tls
lwz 0,28(9)
After mflr, the lwz is missing. r0 has the offset from last lr which is wrong
here.
The RTL in tc.c.185r.cprop_hardreg has the lwz included, the next pass
tc.c.186r.dce does not anymore.
lwz gets not killed if I used -mcpu=power or -mcpu=e300c3. I used -mcpu=8540
which is default for powerpc-linux-gnuspe. -O1 was used in the test case.
The complete cmd line:
/build/bigeasy/gcc-4.4-4.4.4/build/./gcc/xgcc \
-B/build/bigeasy/gcc-4.4-4.4.4/build/./gcc/ \
-B/usr/powerpc-linux-gnuspe/bin/ \
-B/usr/powerpc-linux-gnuspe/lib/ \
-isystem \
/usr/powerpc-linux-gnuspe/include \
-isystem \
/usr/powerpc-linux-gnuspe/sys-include \
-Werror \
-pthread \
-ftls-model=initial-exec \
-O2 \
-pthread \
-fPIC \
-DPIC \
tc.c \
-o \
tc.S \
-S \
-mcpu=8540 \
-O1 \
-fdump-rtl-all \
-c \
A side note: the complete file (parallel.c from libgomp) was compiled with -O2
and the lwz was killed between parallel.c.174r.postreload and
parallel.c.176r.split2.

Confirmed with current 4.4 branch and mainline.
-mabi=nospe -mno=spe doesn't make the problem go away; only
changing -mcpu does.

------- Comment #5 from Kyle dot D dot Moffett at boeing dot com 2010-05-20 04:53 -------
I am not able to reproduce this with a cross-compiling GCC 4.4.3 or 4.4.4 built
from Debian sources. Configuration parameters for GCC 4.4.4 were:
-v
--with-pkgversion='Debian 4.4.4-2'
--with-bugurl='file:///usr/share/doc/gcc-4.4/README.Bugs'
--prefix=/usr
--enable-shared
--enable-multiarch
--enable-linker-build-id
--with-system-zlib
--libexecdir=/usr/lib
--without-included-gettext
--enable-threads=posix
--with-gxx-include-dir=/usr/powerpc-linux-gnuspe/include/c++/4.4.4
--program-suffix=-4.4
--enable-nls
--enable-clocale=gnu
--enable-libstdcxx-debug
--enable-objc-gc
--with-cpu=8548
--enable-e500_double
--with-long-double-128
--disable-multilib
--enable-checking=release
--program-prefix=powerpc-linux-gnuspe-
--includedir=/usr/powerpc-linux-gnuspe/include
--with-headers=/usr/powerpc-linux-gnuspe/include
--with-libs=/usr/powerpc-linux-gnuspe/lib
--build=x86_64-linux-gnu
--host=x86_64-linux-gnu
--target=powerpc-linux-gnuspe
CC=gcc
build_alias=x86_64-linux-gnu
host_alias=x86_64-linux-gnu
target_alias=powerpc-linux-gnuspe
--enable-languages=c,c++,fortran,objc,obj-c++
Versions are:
powerpc-linux-gnuspe-gcc-4.3 (Debian 4.3.4-10 with a patch to debian/rules)
4.3.4
powerpc-linux-gnuspe-gcc-4.4 (Debian 4.4.4-2 with a patch to debian/rules)
4.4.4
The C file was compiled as follows in both cases:
powerpc-linux-gnuspe-gcc -Werror -pthread -ftls-model=initial-exec -O2
-pthread -fPIC -DPIC tc.c -o tc.S -S -mcpu=8540 -O1 -fdump-rtl-all -c
I'm not very familiar with the RTL passes, but if somebody can tell me what
else to look for or test I'll go scrounge around to see if I can find what's
hiding the problem for me.
Cheers,
Kyle Moffett

I don't see the problem with 4.3 .
Kyle, are you sure it doesn't happen for you with 4.4?
I use
powerpc-linux-gnuspe-gcc -Wall -W -O1 -pthread -ftls-model=initial-exec
-mcpu=8540 -fPIC -S t.c -fverbose-asm
paste your output of that?

------- Comment #10 from Kyle dot D dot Moffett at boeing dot com 2010-05-20 12:37 -------
Ok, it looks like the bug was introduced in the 4.4 branch between 4.4.2 and
4.4.4, because my old GCC 4.4.2 compiler works, but the 4.4.4 I built yesterday
after I noticed this report does not.
If needed I can spend some time to track down exactly which optimization
flag(s) cause the problem, but hopefully we've narrowed down the versions
closely enough for it to be easy to find. :-D
Cheers,
Kyle Moffett

This problem can be seen on powerpc-linux-gcc with the options -O1 -fPIC
-ftls-model=initial-exec -misel.
The error occurs between 172r.ira and 174r.postreload, not at 186r.dce as
previously reported.

gcc-4.4 patch
The underlying problem is that the load_toc_v4_PIC_1b rtl doesn't properly
describe that its output depends both on the value of a symbol,
_GLOBAL_OFFSET_TABLE_, and on its location. This could be fixed by using an
unspec_volatile rather than unspec. I chose instead to add a label to the rtl.
