From b883bc873df7f1a8fa3a13800402e1ec8da74328 Mon Sep 17 00:00:00 2001 From: Andrew Kelley Date: Wed, 12 Dec 2018 20:19:46 -0500 Subject: breaking API changes to all readInt/writeInt functions & more * 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 --- src/analyze.cpp | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'src/analyze.cpp') diff --git a/src/analyze.cpp b/src/analyze.cpp index 2f4b173c5f..46686ce772 100644 --- a/src/analyze.cpp +++ b/src/analyze.cpp @@ -401,7 +401,8 @@ ZigType *get_promise_type(CodeGen *g, ZigType *result_type) { } ZigType *get_pointer_to_type_extra(CodeGen *g, ZigType *child_type, bool is_const, - bool is_volatile, PtrLen ptr_len, uint32_t byte_alignment, uint32_t bit_offset_in_host, uint32_t host_int_bytes) + bool is_volatile, PtrLen ptr_len, uint32_t byte_alignment, + uint32_t bit_offset_in_host, uint32_t host_int_bytes) { assert(!type_is_invalid(child_type)); assert(ptr_len == PtrLenSingle || child_type->id != ZigTypeIdOpaque); @@ -6110,6 +6111,8 @@ uint32_t zig_llvm_fn_key_hash(ZigLLVMFnKey x) { return (uint32_t)(x.data.floating.bit_count) * (uint32_t)1953839089; case ZigLLVMFnIdSqrt: return (uint32_t)(x.data.floating.bit_count) * (uint32_t)2225366385; + case ZigLLVMFnIdBswap: + return (uint32_t)(x.data.bswap.bit_count) * (uint32_t)3661994335; case ZigLLVMFnIdOverflowArithmetic: return ((uint32_t)(x.data.overflow_arithmetic.bit_count) * 87135777) + ((uint32_t)(x.data.overflow_arithmetic.add_sub_mul) * 31640542) + @@ -6128,6 +6131,8 @@ bool zig_llvm_fn_key_eql(ZigLLVMFnKey a, ZigLLVMFnKey b) { return a.data.clz.bit_count == b.data.clz.bit_count; case ZigLLVMFnIdPopCount: return a.data.pop_count.bit_count == b.data.pop_count.bit_count; + case ZigLLVMFnIdBswap: + return a.data.bswap.bit_count == b.data.bswap.bit_count; case ZigLLVMFnIdFloor: case ZigLLVMFnIdCeil: case ZigLLVMFnIdSqrt: -- cgit v1.2.3
