This patch makes it so we use "gcc -x assembler-with-cpp" to build our .S files, instead of translating them to .s files and assembling directly. This allows us to use header files and simple symbolic arithmetic more conveniently in .S files, and at the same time reduces the number of temporary files created when building.

# speed testing disabled.

# By setting GRUB_CFG to "grub-test", grub-memtest.iso can instead be used for

# testing the various different boot modes. Upstream GRUB only supports the
|
|
# 16-bit and 32-bit boot protocols, via the "linux16" and "linux" commands.
|
|
# Fedora add support for the EFI handover boot protocols, via the "linuxefi"
|
|
# command, and, since 2019, remove support for the 32-bit protocol, aliasing
|
|
# the "linux" command to either "linux16" or "linuxefi", depending on whether
|
|
# you boot in legacy or EFI mode. Mageia follows Fedora, but restores support
|
|
# for the 32-bit protocol, via the "linux32" command. Other distributions no
|
|
# doubt do their own thing. The boot menu on grub-memtest.iso attempts to
|
|
# support all these options.
