2017-08-22fix compiler test errorsAndrew Kelley
closes #428 Thanks Marc Tiehuis for diagnosing this bug
2017-08-20compile-time f32, f64 operations are now correctly lossyAndrew Kelley
previously we used the bigfloat abstraction to do all compile-time float math. but runtime code and comptime code are supposed to get the same result. so now if you add a f32 to a f32 at compile time it does it with f32 math instead of the bigfloat. float literals still get the bigfloat math. closes #424
2017-08-19add setEvalBranchQuota builtin functionAndrew Kelley
2017-08-19bit shifting safetyAndrew Kelley
* add u3, u4, u5, u6, u7 and i3, i4, i5, i6, i7 * shift operations shift amount parameter type is integer with log2 bit width of other param - This enforces not violating undefined behavior on shift amount >= bit width with the type system * clean up math.log, math.ln, math.log2, math.log10 closes #403
2017-08-17fix big integer shifting by large numberAndrew Kelley
2017-08-17fix wrong value for clz, ctz at compile timeAndrew Kelley
closes #418 also make clz, ctz return smaller integer bit widths and use smaller integer bit widths for enum tag types
2017-08-16compiler_rt implementations for __fixuns* functionsAndrew Kelley
* add u128 and i128 integer types * add f128 floating point type * implement big integer multiplication (See #405)
2017-08-09more intuitive left shift and right shift operatorsAndrew Kelley
Before: * << is left shift, not allowed to shift 1 bits out * <<% is left shift, allowed to shift 1 bits out * >> is right shift, allowed to shift 1 bits out After: * << is left shift, allowed to shift 1 bits out * >> is right shift, allowed to shift 1 bits out * @shlExact is left shift, not allowed to shift 1 bits out * @shrExact is right shift, not allowed to shift 1 bits out Closes #413
2017-08-08add ptrToInt builtin, remove usize(ptr) castAndrew Kelley
closes #415
2017-08-06limit generated C preprocessor tokens to alphabetAndrew Kelley
closes #407 The mangling strategy replaces bytes outside the alphabet with "_xx_" where xx is the hex code of the byte.
2017-08-06fix constant debug info when number literal is 0Andrew Kelley
2017-07-08better bigint/bigfloat implementationAndrew Kelley
2017-06-19workaround for llvm bugAndrew Kelley
See #393 for details
2017-06-14fix compiler segfault on `null ?? x`Andrew Kelley
closes #390
2017-06-14partial implementation of printing floating point numbers with errol3Andrew Kelley
also add bitCast builtin function. closes #387
2017-06-14progress toward windows hello world workingAndrew Kelley
2017-05-27const global values can reference each otherAndrew Kelley
Before, if you did something like: ``` const hi1 = "hi"; const hi2 = hi1; ``` This would create the "hi" data twice in the built object. But since the value is const we don't have to duplicate the data, now we take advantage of this fact. closes #336
2017-05-23building with mingw for windowsAndrew Kelley
2017-05-20flip the enum order of FloatModeAndrew Kelley
2017-05-20add setFloatMode builtin and std.math.floorAndrew Kelley
* 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)
2017-05-17typeId builtin instead of isInteger, isFloat, etcAndrew Kelley
closes #373
2017-05-09inline function call with builtin function instead...Andrew Kelley
...of special syntax. partially reverts 41144a8566a6fbd779403f6b69424bb640c94a7f closes #306
2017-05-07delete @generatedCode builtin functionAndrew Kelley
good riddance
2017-05-07rename c_long_double to c_longdoubleAndrew Kelley
to be consistent with other c primitive type names
2017-05-06builtin functions for division and remainder divisionAndrew Kelley
* add `@divTrunc` and `@divFloor` functions * add `@rem` and `@mod` functions * add compile error for `/` and `%` with signed integers * add `.bit_count` for float primitive types closes #217
2017-05-04add compile error when unable to inline a functionAndrew Kelley
See #38
2017-05-02add safe release build modeAndrew Kelley
closes #288
2017-05-01make debug safety stuff lazyAndrew Kelley
2017-05-01`@import("builtin")` instead of `@compileVar`Andrew Kelley
See #226 Closes #220
2017-04-30zig build: organize build artifactsAndrew Kelley
closes #328
2017-04-30back to AT&T syntax for assemblyAndrew Kelley
this reverts 5c04730534ea7933855429c5fc5dc7b22eba7bc2. sadly the quality of the intel dialect in llvm's assembly parser has many frustrating bugs, and generally has unfortunate syntax. the plan is to use AT&T for now since it at least works, and eventually zig will have its own assembly parser for x86 and it will be as close to NASM as possible.
2017-04-28zig puts temporary object files in zig-cache folderAndrew Kelley
See #298
2017-04-27add no-elim-base-pointer to __zig_fail functionAndrew Kelley
fixes missing frame for unwrapping an error closes #345
2017-04-27zig test no longer requires a separate test_runner.o fileAndrew Kelley
See #298
2017-04-26build system: consolidate duplicate code and moreAndrew Kelley
* add ability to add assembly files when building an exe, obj, or lib * add implicit cast from `[N]T` to `?[]const T` (closes #343) * remove link_exe and link_lib in favor of allowing build_exe and build_lib support no root zig source file
2017-04-25revert the last 3 compile time improvementsAndrew Kelley
they introduced complexity into the compiler and didn't really help. This reverts commit efa771af754281cd76a77ef22af107eb0a9aaf9a. This reverts commit 8614397110595e267b7e4e1f558bfce619e60c02. This reverts commit 13c6a58a61817ae6aae66dd1843385452fe65bd1.

2017-04-24better stack traces for ELF x86_64Andrew Kelley
2017-04-23blocks check that their statements are voidJosh Wolfe
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.
