closes #326
|
|
|
|
* add alignment capability for fn protos
* add @alignCast
* fix some ast rendering code
* fix some ir rendering code
* add error for pointer cast increasing alignment
* update allocators in std to correctly align
See #37
|
|
* remove `@setGlobalAlign`
* add align keyword for setting alignment on functions and
variables.
* loads and stores use alignment from pointer
* memcpy, memset use alignment from pointer
* add syntax for pointer alignment
* slices can have volatile
* add u2, i2 primitives
* ignore preferred align and use abi align everywhere
* back to only having alignOf builtin.
preferredAlignOf is too tricky to be useful.
See #432. Partial revert of

also add bitCast builtin function. closes #387

* skip installing std/rand_test.zig as it's not needed beyond running
the std lib tests
* add std.math.floor function
* add setFloatMode builtin function to choose between
builtin.FloatMode.Optimized (default) and builtin.FloatMode.Strict
(Optimized is equivalent to -ffast-math in gcc)

This changes the error message "return value ignored" to "expression value is ignored".
This is because this error also applies to {1;}, which has no function calls.
Also fix ignored expression values in std and test.
This caught a bug in debug.readAllocBytes where an early Eof error would have been missed.
See #219.

introduce os.EnvMap
|
|
* 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

See #290

* `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

* introduce zigrt file. it contains only weak symbols so that
multiple instances can be merged. it contains __zig_panic
so that multiple .o files can call the same panic function.
* remove `@setFnVisible` builtin and add @setGlobalLinkage builtin
which is more powerful
* add `@panic` builtin function.
* fix collision of symbols with extern prototypes and internal
function names
* add stack protector safety when linking against libc. To add
the safety mechanism without libc requires implementing
Thread Local Storage. See #276

previously, we had lazy analysis of top level declarations,
but if a declaration was referenced within a compile-time
if or switch statement, that would still add the top
level declaration to the resolution queue.
now we have a declref ir instruction, which is only resolved
if we analyze the instruction. this takes into account comptime
branching.
closes #270
|
|
* remove setFnTest builtin
* add test "name" { ... } syntax
* remove --check-unused argument. functions are always lazy now.
|
|
* add `@compileLog(...)` builtin function
- Helps debug code running at compile time
- See #240
* fix crash when there is an error on the start value of a slice
* add implicit cast from int and float types to int and float
literals if the value is known at compile time
* make array concatenation work with slices in addition to
arrays and c string literals
* fix compile error message for something not having field access
* fix crash when `@setDebugSafety()` was called from a
function being evaluated at compile-time
* fix compile-time evaluation of overflow math builtins.
* avoid debug safety panic handler in builtin.o and compiler_rt.o
since we use no debug safety in these modules anyway
* add compiler_rt functions for division on ARM
- Closes #254
* move default panic handler to std.debug so users can
call it manually
* std.io.printf supports a width in the format specifier

..section in the initialization expression

See #238
We can revisit how volatile will work later - for now
here's a builtin function to do it.

closes #241
|
|
See #167
Need to troubleshoot when we send 2 slices to printf. It goes
into an infinite loop.
This commit introduces 4 builtin functions:
* `@isInteger`
* `@isFloat`
* `@canImplictCast`
* `@typeName`
