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