2017-10-25	Try to unbreak Linux sanitizers	Kamil Rytarowski
	Add fallback definition of internal_syscall_ptr and internal_syscall64 for Linux/x86_64 and Linux/aarch64. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@316598 91177308-0d34-0410-b5e6-96231b3b80d8

2013-10-03	asan/msan/tsan: fix broken linux syscalls	Dmitry Vyukov
	Currently the following source code: u64 NanoTime() { kernel_timeval tv = {}; internal_syscall(__NR_gettimeofday, &tv, 0); return (u64)tv.tv_sec * 100010001000 + tv.tv_usec * 1000; } generates the following assembly: Dump of assembler code for function __sanitizer::NanoTime(): => 0x00007ff30657d380 <+0>: lea -0x10(%rsp),%rdi 0x00007ff30657d385 <+5>: xor %esi,%esi 0x00007ff30657d387 <+7>: mov $0x60,%eax 0x00007ff30657d38c <+12>: syscall 0x00007ff30657d38e <+14>: mov $0,%eax 0x00007ff30657d393 <+19>: retq with this change: Dump of assembler code for function __sanitizer::NanoTime(): => 0x00007faab834f380 <+0>: movq $0x0,-0x10(%rsp) 0x00007faab834f389 <+9>: movq $0x0,-0x8(%rsp) 0x00007faab834f392 <+18>: lea -0x10(%rsp),%rdi 0x00007faab834f397 <+23>: xor %esi,%esi 0x00007faab834f399 <+25>: mov $0x60,%eax 0x00007faab834f39e <+30>: syscall 0x00007faab834f3a0 <+32>: mov -0x8(%rsp),%rax 0x00007faab834f3a5 <+37>: mov -0x10(%rsp),%rcx 0x00007faab834f3aa <+42>: imul $0x3e8,%rax,%rdx 0x00007faab834f3b1 <+49>: imul $0x3b9aca00,%rcx,%rax 0x00007faab834f3b8 <+56>: add %rdx,%rax 0x00007faab834f3bb <+59>: retq git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@191908 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-08	[nolibc] Change internal syscall API to remove reliance on libc's errno.	Peter Collingbourne
	This change moves to a model where the error value of a system call is potentially contained in the return value itself rather than being implicit in errno. The helper function internal_iserror can be used to extract the error value from a return value. On platforms other than Linux/x86_64 this still uses errno, but other platforms are free to port their error handling to this new model.
