3	# The Recompiler Sub-Makefile.
4	#
5	# There are a few of complicating factors here, esp. on AMD64 systems:
6	#
7	# * op.c doesn't compile work correctly with gcc 4. For this we've
8	# checked in op.S, which is the reason why we don't compile op.c
9	# directly but always compile via the assembly file.s
10	# * On 64-bit Windows we lack a compiler and have to resort to a
11	# linux cross compiler building an ELF relocatable module which
12	# we then load using a wrapper module. Thus the REM_MOD mess.
13	# * On platforms using the 64-bit GCC ABI, we're not allowed to
14	# generate non-PIC shared objects, and op.c requires the code
15	# to be non-PIC. We apply the same trick as we developed for
16	# 64-bit windows.
