getting error as illegal instruction
garadeaniket opened this issue · comments
Hi ,
After running the ./a.out after compiling the example codes on a64fx using gcc 04level3.c -I /path/to/include/ -L /path/to/lib/ -lblis -lm , i am getting "Illegal instruction(core dumped) error.
Kindly help to resolve the error
Ah, I see you did submit an issue. Reposting from Discord:
Please include the specific version of BLIS used (release number or git commit ID). It would also be helpful if you could:
- Configure and build blis using ./configure -dopt a64fx
- Build your example program using gcc -g
- Run with gdb, gdb ./a.out and enter the following commands:
- r to start the program it should run until the illegal instruction error occurs
- bt to get a backtrace. Please send this information.
- disas this will output a disassembly. You will need the press enter until you get to a page with => to mark the current instruction. Please send this page of output.
Technically 3.iii) can be done on an optimized binary or from the core dump.
Blis version used : blis-0.9.0 , I have also attached the backtrace and dissassemble output after running gdb for blis example 04level3.c.
backtrace.txt
disassemble.txt
It looks like you need to add CFLAGS="-DCACHE_SECTOR_SIZE_READONLY" to the flags passed to configure. E.g. ./configure -tomp CFLAGS="-DCACHE_SECTOR_SIZE_READONLY" a64fx.
Its working .. Thankyou
