The m32r trap code was written for a 32-bit Linux host (and really, one whose Linux ABI matched pretty exactly). This has lead to conversions between integers and pointers which breaks down hard on 64-bit hosts. Clean up some of the functions where possible to avoid unnecessary conversions, use uintptr_t to cast 32-bit target pointers to host pointers in some places, and just stub out a few functions that can't easily be salvaged currently when sizeof(void*) is not 32-bits. This is a bit ugly, but lets us enable warnings for the whole file. |

This is the m32r simulator directory. It is still work-in-progress. The current sources are reasonably well tested and lots of features are in. However, there's lots more yet to come. There are lots of machine generated files in the source directory! They are only generated if you configure with --enable-cgen-maint, similar in behaviour to Makefile.in, configure under automake/autoconf. For details on the generator, see ../../cgen. devo/cgen isn't part of the comp-tools module yet. You'll need to check it out manually (also akin to automake/autoconf).
