gcc-7.3.0: ptxas lib_a-hash_func.o, line 11; fatal : Invalid initial value expression

[Siegmar Gross]

Hi,

today I tried to install gcc-7.3.0 with accelerator support
on my "SUSE Linux Enterprise Server 12.3 (x86_64)" with
gcc-6.4.0. I used the following commands to download and build
everything.

setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:/usr/local/cuda/lib64
setenv CUDA_INC_PATH /usr/local/cuda/include
setenv CUDA_LIB_PATH /usr/local/cuda/lib64
set path = ( ${path} /usr/local/cuda/bin )

git clone https://github.com/MentorEmbedded/nvptx-tools
git clone https://github.com/MentorEmbedded/nvptx-newlib

wget ftp://ftp.gwdg.de/pub/misc/gcc/releases/gcc-7.3.0/gcc-7.3.0.tar.xz
tar xf gcc-7.3.0.tar.xz
cd gcc-7.3.0
ln -s ../nvptx-newlib/newlib newlib
cd ..

mkdir make_nvptx-tools
cd make_nvptx-tools
../nvptx-tools/configure --prefix=/usr/local/gcc-7.3.0 \
   |& tee log.configure
make |& tee log.make
make install |& tee log.make-install
cd ..

mkdir gcc-7.3.0_build
cd gcc-7.3.0_build
../gcc-7.3.0/configure --prefix=/usr/local/gcc-7.3.0 \
   --target=nvptx-none \

   --with-newlib \
   --enable-newlib-io-long-long \
   --enable-languages=c,c++,fortran,lto \
   |& tee log.configure

Unfortunately, "make" breaks with the following error.

I was able to build that part for gcc-7.2.0 with the same commands.

I would be grateful, if somebody knows a solution or can fix the
problem. Do you need anything else? Thank you very much for any
help in advance.


Kind regards

Thanks for providing these (but I have not yet reviewed them in detail,
because the problem might be solved already, see below).

Am I right guessing that you're using CUDA 9?  Then it'd most likely be
the issue discussed in <https://gcc.gnu.org/PR83790> "Update nvptx target
to work with cuda 9".  By now, there has a fix been committed to GCC
trunk, and I assume the same would also work on earlier GCC
releases/branches.

Interesting.  Or, maybe you've not been using CUDA 9 in that build?

Hi Thomas,

thank you very much for your help. I applied the patch to nvptx.c
and was able to build everything. The compiler works for my small
accelerator programs.

loki nvptx 147 diff nvptx.c nvptx.c.orig
1878,1881c1878
<       bool function = SYMBOL_REF_DECL (sym)
<       && (TREE_CODE (SYMBOL_REF_DECL (sym)) == FUNCTION_DECL);
<       if (!function)
<       fprintf (asm_out_file, "generic(");
---
 >       fprintf (asm_out_file, "generic(");
1883,1886c1880
<       if (!function)
<       fprintf (asm_out_file, val ? ") + " : ")");
<       else if (val)
<       fprintf (asm_out_file, " + ");
---
 >       fprintf (asm_out_file, val ? ") + " : ")");
loki nvptx 148


I'm not sure if I used CUDA 8 or CUDA 9 to build gcc-7.2.0, but I
assume it was already CUDA 9.

loki nvptx 148 ls -ld /usr/local/gcc-7.2.0/ /usr/local/cuda
lrwxrwxrwx 1 root root    8 Sep 27 09:15 /usr/local/cuda -> cuda-9.0
drwxr-xr-x 9 root root 4096 Nov  2 12:07 /usr/local/gcc-7.2.0/
loki nvptx 149


Thank you very much once more

Siegmar
