From 788d5e24ca19c6291cebd8d1ad5b5ed6abf42665 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 10 Apr 2019 20:11:19 -0400 Subject: remove external __syscall function and last remaining users 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. --- src/thread/__syscall_cp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/thread') diff --git a/src/thread/__syscall_cp.c b/src/thread/__syscall_cp.c index af666f06..42a01674 100644 --- a/src/thread/__syscall_cp.c +++ b/src/thread/__syscall_cp.c @@ -7,7 +7,7 @@ static long sccp(syscall_arg_t nr, syscall_arg_t u, syscall_arg_t v, syscall_arg_t w, syscall_arg_t x, syscall_arg_t y, syscall_arg_t z) { - return (__syscall)(nr, u, v, w, x, y, z); + return __syscall(nr, u, v, w, x, y, z); } weak_alias(sccp, __syscall_cp_c); -- cgit v1.2.1
