Josh Wolfe 0594487a2e fix else-if parsing

Josh Wolfe 4b9e782d37 fix confusion in block expression parsing
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.

See #290
2017-03-31 06:18:20 -04:00
Andrew Kelley 3ca027ca82 first pass at zig build system
* `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
2017-03-31 05:55:41 -04:00
Andrew Kelley a32b5929cc add stack protector safety when linking libc
* 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

Andrew Kelley 6dba1f1c8e slice and array re-work plus some misc. changes
* `@truncate` builtin allows casting to the same size integer.
   It also performs two's complement casting between signed and
   unsigned integers.
 * The idiomatic way to convert between bytes and numbers is now
   `mem.readInt` and `mem.writeInt` instead of an unsafe cast.
   It works at compile time, is safer, and looks cleaner.
 * Implicitly casting an array to a slice is allowed only if the
   slice is const.
 * Constant pointer values know if their memory is from a compile-
   time constant value or a compile-time variable.
 * Cast from [N]u8 to []T no longer allowed, but [N]u8 to []const T
   still allowed.
 * Fix inability to pass a mutable pointer to comptime variable at
   compile-time to a function and have the function modify the
   memory pointed to by the pointer.
 * Add the `comptime T: type` parameter back to mem.eql. Prevents
   accidentally creating instantiations for arrays.
2017-02-12 17:35:51 -05:00
Andrew Kelley fc100d7b3b lots of miscellaneous things all in one big commit
* 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

Andrew Kelley b78c91951a remove ability to mark if and switch as inline
if and switch are implicitly inline if the condition/target
expression is known at compile time.

instead of:

```
inline if (condition) ...
inline switch (target) ...
```

one can use:

```
if (comptime condition) ...
switch (comptime target) ...
```
