annotate dyncallback/dyncall_callback_arm32_thumb_gas.S @ 533:71c884e610f0
- integration of patches from Raphael Luba, Thekla, Inc.:
* integration of aggregate-by-value (struct, union) support patch for x64 (win and sysv)
* windows/x64 asm additions to specify how stack unwinds (help for debuggers, exception handling, etc.)
* see Changelog for details
- new calling convention modes for thiscalls (platform agnostic, was specific before)
* new signature character for platform agnostic thiscalls ('*' / DC_SIGCHAR_CC_THISCALL)
- dcCallF(), dcVCallF(), dcArgF() and dcVArgF():
* added support for aggregates-by-value (wasn't part of patch)
* change that those functions don't implicitly call dcReset() anymore, which was unflexible (breaking change)
- added macros to feature test implementation for aggregate-by-value and syscall support
- changed libdyncall_s.lib and libdyncallback_s.lib order in callback test makefiles, as some toolchains are picky about order
- doc:
* man page updates to describe aggregate interface
* manual overview changes to highlight platforms with aggregate-by-value support
- test/plain: replaced tests w/ old/stale sctruct interface with new aggregate one
