# Almost all of the x86 assembly code in src/trusted is written using
# GNU/AT&T syntax.  On Windows, this means it has to be built using a
# nonstandard toolchain (GNU binutils rather than MSVC).  Each place in
# src/trusted where there is some assembly code puts the assembly code into
# a separate source_set and then pulls that into a larger source_set using
# deps = [ ":foo_asm($nacl_asm_toolchain)" ].  On Windows, this will get a
# special toolchain for running the GNU assembler.  On non-Windows, this is
# just the regular toolchain.
