https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=292421 --- Comment #2 from Stefan Schlosser <bsdcode@disroot.org> --- > 1) The port uses the xbyak git submodule with the version pinned in the flycast > repo instead of the devel/xbyak port, because flycast crashes upon starting a game > with newer xbyak versions. I still have to investigate this issue and it's not > clear if it's a regression in xbyak, flycast or somewhere else. The experienced crash is a thrown exception ERR_BAD_MEM_SIZE from xbyak. This exception gets thrown after introducing a new check for matching sizes of register and memory operands in the opMR function: https://github.com/herumi/xbyak/commit/de4ad6b96434592b9da6a286d717794b5d5f5cf8 This commit was made directly after the pinned submodule version in the flycast repo, so any newer xbyak version will trigger this exception in flycast. The macro XBYAK_STRICT_CHECK_MEM_REG_SIZE was introduced later to disable exactly this check: https://github.com/herumi/xbyak/commit/86389781d918071b3c35640e082cc76eed400b59 I tested flycast with the devel/xbyak port and setting XBYAK_STRICT_CHECK_MEM_REG_SIZE=0 for compilation. This prevents the crash. But this macro has a comment that it may be removed in future version of xbyak, therefore I currently don't want to depend on it for flycast. Ultimatly, upstream flycast will have to address this if/when it updates the xbyak submodule. In conclusion, we should keep using the xbyak submodule instead of the devel/xbyak port for now. -- You are receiving this mail because: You are the assignee for the bug.home | help
