Does MSVC follow the AAPCS64 for varargs? https://github.com/ARM-software/abi-aa/blob/main/aapcs64/aapcs64.rst#id120 If not, then I don't think this is fixable. If it does, then we need to fix the VA_LIST definitions for _M_ARM64. -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
