# Copy this template to your game project root and customize:
#   1. Change the project name below
#   2. Set XBOXRECOMP_DIR to where you cloned xboxrecomp
#   3. Adjust source file lists as you add game-specific code
#   4. Add any game-specific compile definitions or link libraries

# Collect generated recompiled code.
# The recomp pipeline outputs files into src/recomp/gen/.
# With --split 1000, you get gen_0000.c, gen_0001.c, etc.
# CONFIGURE_DEPENDS so re-running the recompiler picks up added/removed files
# without a manual re-configure. A plain GLOB is evaluated once at configure
# time, so a newly generated file (an extra chunk, recomp_stubs_unresolved.c)
# is silently left out of the build and shows up as unresolved externals.

#   src/recomp/recomp_dispatch.h     - binary search dispatch table
#   src/recomp/recomp_types.h        - register model, ICALL macros, MEM helpers
