Andrew Kelley	47a0e3ec5e	Merge pull request #4871 from boothby/issue4769 ... Address bugs when //, /// or //! are immediately followed by EOF	2020-03-31 10:56:21 -04:00
Andrew Kelley	839d85e440	fixes to 32-bit handling, to support 32-bit arm	2020-03-31 10:10:31 -04:00
Kelly Boothby	1111d3ad13	fixed bugs hitting EOF immediately after //, /// or //!	2020-03-30 18:30:03 -07:00
Andrew Kelley	cfedd3aca2	revert detection of rtti and exceptions ... This caused link errors in c++ code because it was not correct to pass these flags to child codegens. And that was the only reason to detect these flags. Otherwise we can safely rely on non-explicitly-detected flag forwarding.	2020-03-30 17:42:30 -04:00
Andrew Kelley	6408766d6b	linking: remove check for target_supports_libunwind ... I'm not sure why this was ever there. Maybe it was working around a problem with LLVM 9. Anyway this fixes linking C++ code for 32 bit arm and riscv.	2020-03-30 15:50:53 -04:00
Andrew Kelley	b980568c81	add peer type resolution for mixed-const []T and *[N]T ... closes #4766 This commit also fixes the implementation of some utility functions for adjusting properties of pointer types. Previously these functions would incorrectly drop vector, sentinel, and inference metadata.	2020-03-30 13:02:50 -04:00
LemonBoy	c1cc1ebc35	ir: Avoid constant-folding ptr to sentinels ... Constant-folding the pointers to the expected sentinel value have some big problems: it hides the real content of the array, makes the pointer to the sentinel point to a completely different memory region and treats it like a const value even when the underlying array is mutable. Fixes #4840	2020-03-30 11:03:56 -04:00

Ryan Liptak	874b4618ca	zig cc: Add support for -z ... This is only the first step; it makes zig cc recognize -z and append it to the linker args, but the linker arg parsing doesn't support -z yet so it will just give the warning 'unsupported linker arg: -z'	2020-03-28 00:35:54 -07:00
Ryan Liptak	b0b29b8a2f	zig cc: Add support for -Xlinker, --for-linker, --for-linker=	2020-03-27 23:32:01 -07:00

Andrew Kelley	fae6cf0961	improved handling of native system directories ... * `-isystem` instead of `-I` for system include directories fixes a problem with native system directories interfering with zig's bundled libc. * separate Stage2Target.is_native into Stage2Target.is_native_os and Stage2Target.is_native_cpu.	2020-03-25 20:34:15 -04:00
