MACHINE_ABI is a list of properties of the ABI used for MACHINE_ARCH. It should be used in place of long conditionals on MACHINE_ARCH where practical. The following properties are indicated with one of the follow values: Byte order: big-endian, little-endian Floating point ABI: soft-float, hard-float Size of long (size_t, etc): long32, long64 Pointer type: ptr32, ptr64 Size of time_t: time32, time64 For example, i386 targets will be: MACHINE_ABI= big-endian hard-float long32 ptr32 time32 Reviewed by: imp Obtained from: CheriBSD Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D36421
