Here is a diff unbreaking desmume. I am attaching it because it contains ^M being removed from an existing patch. I came across this same issue with my WIP-port of flycast. It has to be adapted for immutable userland mappings in 7.2 -current. Globals are in BSS and are immutable by default. They need to be marked as mutable in order for mprotect RWX to work. I took this fix from syzkaller. see: https://github.com/google/syzkaller/commit/bc009f82ea71c399f19eef28f115ff5cda7be4ba flycast had to be patched in three places. see: https://www.namtsui.com/cgi-bin/cvsweb/ports/emulators/flycast/patches/patch-core_hw_aica_dsp_x64_cpp?rev=1.6&content-type=text/x-cvsweb-markup https://www.namtsui.com/cgi-bin/cvsweb/ports/emulators/flycast/patches/patch-core_hw_arm7_arm7_rec_cpp?rev=1.6&content-type=text/x-cvsweb-markup https://www.namtsui.com/cgi-bin/cvsweb/ports/emulators/flycast/patches/patch-core_hw_sh4_dyna_driver_cpp?rev=1.6&content-type=text/x-cvsweb-markup This unbreaks the emulator with my testing of Chrono Trigger. Feedback and tests are welcome. OK?
