2020-08-13stage2: implement while loops (bool condition)Andrew Kelley
* introduce a dump() function on Module.Fn which helpfully prints to stderr the ZIR representation of a function (can be called before attempting to codegen it). This is a debugging tool. * implement x86 codegen for loops * liveness: fix analysis of conditional branches. The logic was buggy in a couple ways: - it never actually saved the results into the IR instruction (fixed now) - it incorrectly labeled operands as dying when their true death was after the conditional branch ended (fixed now) * zir rendering is enhanced to show liveness analysis results. this helps when debugging liveness analysis. * fix bug in zir rendering not numbering instructions correctly closes #6021

2019-12-16std: lessThan and greaterThan between signed and unsignedShawn Landden
It is a deviation from C, but I think we should consider making this the behavior of the operators. See #2133
2019-12-10Replace @typeOf with @TypeOf in all zig sourceRobin Voetter
This change was mostly made with `zig fmt` and this also modified some whitespace. Note that in some files, `zig fmt` produced incorrect code, so the change was made manually.
2019-11-29std.math: remove constants that should be expressionsAndrew Kelley
All four of these can be represented in fewer characters with expressions, which will be guaranteed to happen at compile-time, and have the same or better precision. The other math constants here which depend on function calls could be similarly removed if and when #425 is solved. However I left them for now since Zig does not eagerly evaluate functions with comptime parameters.
