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: Another hack for the C ABI compatibilityLemonBoy
Applying the wrong ABI is slightly better than using the Zig ABI, the whole thing is so wrong it should be burned to the ground.
2020-04-20stage1: Fix wrong union accessLemonBoy
Thanks to @frett27 on irc for reporting the compiler would segfault when run on ARM.
2020-04-17stage1: Fix several bugs in constant generationLemonBoy
The codegen would sometimes change the LLVM type for some constants to an unnamed structure in order to accomodate extra padding. This is fine as long as the alignment of each field is still respected and it was not the case for structure types, leading to ill-formed constants being generated. Optional types suffer from this to a lower extent as their layout is quite lucky, the only missing piece was the tail padding. Closes #4530 Closes #4594 Closes #4295 Closes my will to live
2020-04-13stage1: More fixes for BE targetsLemonBoy
* Fix packed struct alignment * Adjust some tests
2020-04-12only use `-nostdinc++` on c++ filesMichael Dusan
This is a follow-up to d27ef1aaef8ac12801ba4e6c2ed748c7151096a7 and avoids compiler warnings: warning: argument unused during compilation: '-nostdinc++'
2020-04-12Zig treats -lstdc++ identically to -lc++Andrew Kelley
Thanks to Michael Dusan for figuring out what was happening here. closes #5012
2020-04-07Merge pull request #4857 from LemonBoy/fix-4777Andrew Kelley
Rewrite the bound checks in slice operator
2020-04-07stage1: Respect the specified name for extern varLemonBoy
Extend the logic used for function definitions to variables. Closes #4947
2020-04-06zig cc: recognize a few more linker optionsAndrew Kelley
* `--major-image-version` * `--minor-image-version` * `--stack`
2020-04-05ir: Fix error checking for vector opsLemonBoy
The extra logic that's needed was lost during a refactoring, now it should be fine.
2020-04-05ir: Remove unused and commented out codeLemonBoy
2020-04-05ir: Support shift left/right on vectorsLemonBoy
2020-04-05ir: Support div/mod/rem on vector typesLemonBoy
Closes #4050
2020-04-05Do not parse native_libc.txt anymore when linking on native target, always ↵Michaël Larouche
run detection of libc. Fixes #4772
2020-04-03change the default ABI of riscv64-linux-muslAndrew Kelley
Before, this would cause a link failure when mixing Zig and C code for RISC-V targets. Now, the ABIs match and Zig and C code can be mixed successfully. I will file a follow-up issue for the ability to deal more explicitly with ABIs. closes #4863
2020-04-03ir: Rewrite the bound checks in slice operatorLemonBoy
Closes #4777
2020-04-02zig cc: support more linker argsAndrew Kelley
2020-04-02zig cc: respect -MF -MV -MD optionsAndrew Kelley
Zig disables its caching and forwards these args when any are provided. see #4784
2020-04-01zig cc properly handles -S flag and .ll, .bc extensionsAndrew Kelley
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.
2020-04-01fixups and revert a few thingsAndrew Kelley
2020-04-01Use length field as passed in stage2 libc_installation instead of relying on ↵daurnimator
zero termination
2020-03-30revert detection of rtti and exceptionsAndrew Kelley
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.
2020-03-27zig c++: get it working with musl and mingw-w64Andrew Kelley
2020-03-26ability to compile c++ hello world with `zig c++`Andrew Kelley
closes #4786
2020-03-25improved handling of native system directoriesAndrew Kelley
* `-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.

2020-03-19ir: More changes to sentinel-terminated const arraysLemonBoy
* 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.
2020-03-18ir: Correct ABI size calculation for arraysLemonBoy
Zero-length array with a sentinel may not have zero size. Closes #4749
