before this commit, the optimized IR code that is displayed in
--verbose mode is not actually what gets emitted to an object
file.
that is now corrected, and we make sure to run the alwaysinliner
pass even in debug mode, so you can rely on "inline" keyword
inlining a function, guaranteed.
See #306
where Int is an integer type
also introduce `@intToPtr` builtin for converting a usize
to a pointer. users now have to use this instead of `(&T)(int)`.
closes#311
* Fix assertion failure when switching on type.
Closes#310
* Update zig build system to support user defined options.
See #204
* fmt.format supports {sNNN} to set padding for a buffer arg.
* add std.fmt.bufPrint and std.fmt.allocPrint
* std.hash_map.HashMap.put returns the previous value
* add std.mem.startsWith
* See #204 - zig build system
* allow builtin types Os, Environ, Arch to be used at runtime.
they have zero_bits=false and debug info now.
* Eradicate use of `@alloca` in std for syscalls. See #225
* add `std.io.writeFile`
* `std.debug.panic` adds a newline to format
* In-progress os.ChildProcess.spawn implementation. See #204
* Add explicit cast from integer to error. Closes#294
* fix casting from error to integer
* fix compiler crash when initializing variable to undefined
with no type
implicit semicolon rules apply recursively to the "else" clause of if and try
if (a) {} else {} // implicit semicolon
if (a) {} else if (a) {} // implicit semicolon
if (a) {} else while (a) {} // implicit semicolon
closes#292
* if, try, while, for, comptime, defer are "greedy" with {} blocks,
meaning if their bodies are blocks, then no suffix operator is allowed
after the block. The {} block gets "built into" the containing statement,
like the body of a switch statement.
* the Expression syntactic element is no longer "greedy" with {} blocks,
meaning it's possible to have suffix operators after {} blocks without
needing the {} block to be an rhs operand first.
* Don't insert void statements all over the place. {} now stays as
{} instead of {{}}, and {;} becomes {} instead of {{};{}}.
* Ensure final statement is always the return value statement, or
the block is empty. This means {label:} becomes {label:{}}.
* `zig build --export [obj|lib|exe]` changed to `zig build_obj`,
`zig build_lib` and `zig build_exe` respectively.
* `--name` parameter is optional when it can be inferred from the
root source filename. closes#207
* `zig build` now looks for `build.zig` which interacts with
`std.build.Builder` to describe the targets, and then the zig
build system prints TODO: build these targets. See #204
* add `@bitcast` which is mainly used for pointer reinterpret
casting and make explicit casting not do pointer reinterpretation.
Closes#290
* fix debug info for byval parameters
* sort command line help options
* `std.debug.panic` supports format string printing
* add `std.mem.IncrementingAllocator`
* fix const ptr to a variable with data changing at runtime.
closes#289
