Josh Wolfe c6605cba83 blocks check that their statements are void
closes #291

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.

Andrew Kelley e3c524c1d4 rename `@ptrcast` to `@ptrCast` to follow convention 2017-04-21 10:39:13 -04:00
Andrew Kelley f7e9d7aa5d ability to implicitly cast integer literal to &const Int
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)`.

Andrew Kelley c400cb429a zig build system: add setLinkerScript and setTarget
* 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

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.

Andrew Kelley d6856859d3 improvements for windows and libc integration
* standard library knows if it is linking against libc and will
   sometimes call libc functions in that case instead of providing
   redundant definitions
 * fix infinite loop bug when resolving use declarations
 * allow calling the same C function from different C imports.
   closes #277
 * push more logic from compiler to std/bootstrap.zig
 * standard library provides way to access errno
   closes #274
 * fix compile error in standard library for windows
 * add implementation of getRandomBytes for windows

Andrew Kelley 9eb29e81f9 rename CBuf to Buffer0 and some minor std API changes 2017-02-28 03:07:11 -05:00
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.

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
2017-02-09 03:09:25 -05:00
Andrew Kelley 07a71fc322 improved behavior on debug safety crash
* instead of emitting a breakpoint for a debug safety crash,
   zig calls a panic function which prints an error message
   and a stack trace and then calls abort.
 * on freestanding OS, this panic function has a default
   implementation of a simple infinite loop.
 * users can override the panic implementation by providing
   `pub fn panic(message: []const u8) -> unreachable { }`
 * workaround for LLVM segfaulting when you try to use cold
   calling convention on ARM.

Andrew Kelley 4b3f18de3c printf var args proof of concept
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`

alter cf9b21c09f MacOSX compatibility
- Implemented some syscall for MacOSX
- tested on : El Capitan 10.11 x86_64
- make self hosted test run on macosx
- modified run_test so it does not fail when parseh throws
  warnings (most of them are related to buildin types from
  gcc that arent defined in header files and unions)
- making -mmacosx-version-min and -mios-version-min works like
  gcc (command line paramers have precedence over enviroment variables)
