2020-04-24stage1: Prevent the creation of illegal ptr typesLemonBoy
Closes #5140
2020-04-23stage1: fix crash on accessing an array of size zero with runtime indexxackus
2020-04-23stage1: Fix bitcast of immediate to ptr type (#5131)LemonBoy
Consider a (legal according to the `@bitCast` rules) conversion from u16 to [2]u8: since the former is a scalar and the latter is a pointer (arrays are represented at pointers in the codegen phase) we have to allocate a temporary slot on the stack and then bitcast the resulting pointer to the desired destination type. Beware that this means the lifetime of the resulting value is the same of the function it's contained in and for all intents and purposes should be regarded as a local (eg. it should not escape). Closes #4395 Closes #5121

2020-04-22stage1: Prevent the creation of illegal pointer typesLemonBoy
Changing the pointer length from Unknown to Single/C now resets the sentinel value too. Closes #5134

2020-04-01ir: Fix comparison of ?T valuesLemonBoy
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
2020-04-01stage1: make C++ switch fallthrough an errorMichael Dusan
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.
2020-04-01Make sure that ZigTypeVector and ZigTypeArray have the same memory layoutTimon Kruiper
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.
2020-04-01Fix some nullptr dereferences on arm-linux-musleabhifTimon Kruiper
2020-03-30add peer type resolution for mixed-const []T and *[N]TAndrew Kelley
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.
2020-03-30ir: Avoid constant-folding ptr to sentinelsLemonBoy
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
