2019-02-04fix vector debug info tripping LLVM assertionAndrew Kelley
2019-02-04SIMD: array to vector, vector to array, wrapping int addAndrew Kelley
also vectors and arrays now use the same ConstExprVal representation See #903
2019-01-30introduce vector type for SIMDAndrew Kelley
See #903 * create with `@Vector(len, ElemType)` * only wrapping addition is implemented This feature is far from complete; this is only the beginning.
2019-01-29backport copy elision changesAndrew Kelley
This commit contains everything from the copy-elision-2 branch that does not have to do with copy elision directly, but is generally useful for master branch. * All const values know their parents, when applicable, not just structs and unions. * Null pointers in const values are represented explicitly, rather than as a HardCodedAddr value of 0. * Rename "maybe" to "optional" in various code locations. * Separate DeclVarSrc and DeclVarGen * Separate PtrCastSrc and PtrCastGen * Separate CmpxchgSrc and CmpxchgGen * Represent optional error set as an integer, using the 0 value. In a const value, it uses nullptr. * Introduce type_has_one_possible_value and use it where applicable. * Fix debug builds not setting memory to 0xaa when storing undefined. * Separate the type of a variable from the const value of a variable. * Use copy_const_val where appropriate. * Rearrange structs to pack data more efficiently. * Move test/cases/* to test/behavior/* * Use `std.debug.assertOrPanic` in behavior tests instead of `std.debug.assert`. * Fix outdated slice syntax in docs.

2019-01-02@bitreverse intrinsic, part of #767 (#1865)vegecode
* bitreverse - give bswap behavior * bitreverse, comptime_ints, negative values still not working? * bitreverse working for negative comptime ints * Finished bitreverse test cases * Undo exporting a bigint function. @bitreverse test name includes ampersand * added docs entry for @bitreverse

2018-12-12breaking API changes to all readInt/writeInt functions & moreAndrew Kelley
* add `@bswap` builtin function. See #767 * comptime evaluation facilities are improved to be able to handle a `@ptrCast` with a backing array. * `@truncate` allows "truncating" a u0 value to any integer type, and the result is always comptime known to be `0`. * when specifying pointer alignment in a type expression, the alignment value of pointers which do not have addresses at runtime is ignored, and always has the default/ABI alignment * threw in a fix to freebsd/x86_64.zig to update syntax from language changes * some improvements are pending #863 closes #638 closes #1733 std lib API changes * io.InStream().readIntNe renamed to readIntNative * io.InStream().readIntLe renamed to readIntLittle * io.InStream().readIntBe renamed to readIntBig * introduced io.InStream().readIntForeign * io.InStream().readInt has parameter order changed * io.InStream().readVarInt has parameter order changed * io.InStream().writeIntNe renamed to writeIntNative * introduced io.InStream().writeIntForeign * io.InStream().writeIntLe renamed to writeIntLittle * io.InStream().writeIntBe renamed to writeIntBig * io.InStream().writeInt has parameter order changed * mem.readInt has different parameters and semantics * introduced mem.readIntNative * introduced mem.readIntForeign * mem.readIntBE renamed to mem.readIntBig and different API * mem.readIntLE renamed to mem.readIntLittle and different API * introduced mem.readIntSliceNative * introduced mem.readIntSliceForeign * introduced mem.readIntSliceLittle * introduced mem.readIntSliceBig * introduced mem.readIntSlice * mem.writeInt has different parameters and semantics * introduced mem.writeIntNative * introduced mem.writeIntForeign * mem.writeIntBE renamed to mem.readIntBig and different semantics * mem.writeIntLE renamed to mem.readIntLittle and different semantics * introduced mem.writeIntSliceForeign * introduced mem.writeIntSliceNative * introduced mem.writeIntSliceBig * introduced mem.writeIntSliceLittle * introduced mem.writeIntSlice * removed mem.endianSwapIfLe * removed mem.endianSwapIfBe * removed mem.endianSwapIf * added mem.littleToNative * added mem.bigToNative * added mem.toNative * added mem.nativeTo * added mem.nativeToLittle * added mem.nativeToBig

2018-09-20better string literal caching implementationAndrew Kelley
We were caching the ConstExprValue of string literals, which works if you can never modify ConstExprValues. This premise is broken with `comptime var ...`. So I implemented an optimization in ConstExprValue arrays, where it stores a `Buf *` directly rather than an array of ConstExprValues for the elements, and then similar to array of undefined, it is expanded into the canonical form when necessary. However many operations can happen directly on the `Buf *`, which is faster. Furthermore, before a ConstExprValue array is expanded into canonical form, it removes itself from the string literal cache. This fixes the issue, because before an array element is modified it would have to be expanded. closes #1076
