| 22 | # This Makefile is aimed at helping GCC validation, for ARM and |
| 23 | # AArch64 targets. |
| 24 | # For example: |
| 25 | # $ make -f Makefile.gcc clean |
| 26 | # $ make -f Makefile.gcc CC.gccarm=/path/to/gcc check |
| 27 | # Note that this will use qemu-system-arm as execution engine which |
| 28 | # may not be what you want. |
| 29 | # Alternatively: |
| 30 | # $ make -f Makefile.gcc clean |
| 31 | # $ make -f Makefile.gcc CC.gccarm=/path/to/gcc compute_ref.gccarm |
| 32 | # $ /path/to/qemu -L /path/to/sysroot/lib compute_ref.gccarm |
| 33 | # $ diff stm-arm-neon.gccarm ref-rvct-neon.txt |
