From eca335fc0453d3680fd9f112574919e13fab31d2 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Mon, 6 Jan 2014 22:05:54 -0500 Subject: eliminate explicit (long) casts when making syscalls this practice came from very early, before internal/syscall.h defined macros that could accept pointer arguments directly and handle them correctly. aside from being ugly and unnecessary, it looks like it will be problematic when we add support for 32-bit ABIs on archs where registers (and syscall arguments) are 64-bit, e.g. x32 and mips n32. --- src/thread/__wait.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/thread/__wait.c') diff --git a/src/thread/__wait.c b/src/thread/__wait.c index 041a0669..a1e47804 100644 --- a/src/thread/__wait.c +++ b/src/thread/__wait.c @@ -10,6 +10,6 @@ void __wait(volatile int *addr, volatile int *waiters, int val, int priv) } if (waiters) a_inc(waiters); while (*addr==val) - __syscall(SYS_futex, (long)addr, FUTEX_WAIT|priv, val, 0); + __syscall(SYS_futex, addr, FUTEX_WAIT|priv, val, 0); if (waiters) a_dec(waiters); } -- cgit v1.2.1
