# 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

# Use '*' rather than '%' in these rules:
# - using '%' does not make them add to the implicit rules above (they
# are different rules, only the 1st one matches)
# - they are needed only when the target already exists, so the
# wildcard matches when needed.
# - if the target does not already exist, the implicit rules apply.
