musl/src/internal/mips64, branch master musl - an implementation of the standard library for Linux-based systems remove external __syscall function and last remaining users 2019-04-11T00:11:19+00:00 Rich Felker dalias@aerifal.cx 2019-04-11T00:11:19+00:00 788d5e24ca19c6291cebd8d1ad5b5ed6abf42665 the weak version of __syscall_cp_c was using a tail call to __syscall to avoid duplicating the 6-argument syscall code inline in small static-linked programs, but now that __syscall no longer exists, the inline expansion is no longer duplication. the syscall.h machinery suppported up to 7 syscall arguments, only via an external __syscall function, but we presently have no syscall call points that actually make use of that many, and the kernel only defines 7-argument calling conventions for arm, powerpc (32-bit), and sh. if it turns out we need them in the future, they can easily be added.
