LemonBoy	6695fa4f32	ir: Fix comparison of ?T values ... The code assumed that every ?T had a pointer child type T, add some more checks to make sure the type is effectively a pointer. Closes #4789	2020-04-01 15:56:38 -04:00
Michael Dusan	212e2354b8	stage1: make C++ switch fallthrough an error ... Make fallthrough an error when compiler supports it. This requires a new macro that is defined with such compilers to be used as a statement, at all fallthrough sites: switch (...) { case 0: ... ZIG_FALLTHROUGH; case 1: ... break; default: ... break; } If we ever move to C++17 as minimal requirement, then the macro can be replaced with `[[fallthrough]];` at statement sites.	2020-04-01 15:56:00 -04:00
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	d9cf779b47	Fix some nullptr dereferences on arm-linux-musleabhif	2020-04-01 20:38:32 +02:00
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
Andrew Kelley	0d4354324c	fix behavior tests compile error on i386-linux	2020-03-26 12:54:59 -04:00

Andrew Kelley	7fa88cc0a6	std lib fixups for new semantics ... std lib tests are passing now	2020-03-19 09:53:55 -04:00
Andrew Kelley	2164b511cc	partial revert of an improvement this branch made ... because it uncovered a result location bug, and I need to get this branch merged before going into a result location rabbit hole. also fix the result type of slicing when the indexes are runtime known and the result should be sentinel terminated.	2020-03-19 09:53:55 -04:00
Andrew Kelley	8688c43745	when result loc is a slice, avoid evaluating lazy start..end ... This prevents lazy values from being unnecessarily evaluated.	2020-03-19 09:53:55 -04:00

LemonBoy	e3c92d0532	ir: More changes to sentinel-terminated const arrays ... * Don't add an extra slot for the sentinel. Most of the code keeps using the constant value from the type descriptor, let's harmonize all the code dealing with sentinels. * Properly write out sentinel values when reinterpreting pointers at comptime. * Allow the reading of the 0th element in a `[0:S]T` type.	2020-03-19 09:53:30 -04:00
