annotate dyncall/dyncall_call_arm32_arm.h @ 27:523c45dfa8fb
- refactored arm calling conventions' callvm code, so that the code that keeps
the caller from overwriting the return value on some platforms also works on
OpenBSD (before we casted the function pointer to have long long as return
type, to hint the caller that there is one, but that triggers an intentional
SIGABRT on OpenBSD for security reasons; now the decl reflects this, directly)
