getting error as illegal instruction about blis HOT 4 CLOSED

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:

1. Configure and build blis using ./configure -dopt a64fx
2. Build your example program using gcc -g
3. Run with gdb, gdb ./a.out and enter the following commands:
   1. r to start the program it should run until the illegal instruction error occurs
   2. bt to get a backtrace. Please send this information.
   3. 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.

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.
