Timon Kruiper	d33766e6c7	Make sure that ZigTypeVector and ZigTypeArray have the same memory layout ... Throughout the stage1 code it is assumed that these have the same layout, but that was not the case. This caused an issue on 32-bit hardware.	2020-04-01 20:50:13 +02:00
Timon Kruiper	ae6965a4e7	Fix undefined behavior when shift amount is 64	2020-04-01 20:50:09 +02:00
Timon Kruiper	d9cf779b47	Fix some nullptr dereferences on arm-linux-musleabhif	2020-04-01 20:38:32 +02:00
Timon Kruiper	9e019ed26b	Fix possible unaligned ptr from getauxval ... This caused SIGILL on armv7a-linux	2020-03-31 15:26:06 -04:00
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
