[builtin] Fixed definitions of builtins that rely on the int/long long type is 32/64 bits Summary: The definition of the builtins __builtin_bswap32, __builtin_bitreverse32, __builtin_rotateleft32 and __builtin_rotateright32 rely on that the int type is 32 bits wide on the target. The defintions of the builtins __builtin_bswap64, __builtin_bitreverse64, __builtin_rotateleft64, and __builtin_rotateright64 rely on that the long long type is 64 bits wide. On targets where this is not the case (e.g. AVR) clang will generate faulty code (wrong llvm assembler intrinsics). This patch add support for using 'Z' (the int32_t type) in Bultins.def. The builtins above are changed to be based on the int32_t type instead of the int type, and the int64_t type instead of the long long type. The AVR backend (experimental) have a native int type that is only 16 bits wide. The supplied testcase will therefore fail if running the testcase on trunk as clang will convert e.g. __builtin_bitreverse32 into llvm.bitreverse.i16 on AVR.

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

[builtin] Fixed definitions of builtins that rely on the int/long long type is 32/64 bits Summary: The definition of the builtins __builtin_bswap32, __builtin_bitreverse32, __builtin_rotateleft32 and __builtin_rotateright32 rely on that the int type is 32 bits wide on the target. The defintions of the builtins __builtin_bswap64, __builtin_bitreverse64, __builtin_rotateleft64, and __builtin_rotateright64 rely on that the long long type is 64 bits wide. On targets where this is not the case (e.g. AVR) clang will generate faulty code (wrong llvm assembler intrinsics). This patch add support for using 'Z' (the int32_t type) in Bultins.def. The builtins above are changed to be based on the int32_t type instead of the int type, and the int64_t type instead of the long long type. The AVR backend (experimental) have a native int type that is only 16 bits wide. The supplied testcase will therefore fail if running the testcase on trunk as clang will convert e.g. __builtin_bitreverse32 into llvm.bitreverse.i16 on AVR.

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

// CHECK: i64 @llvm.bswap.i64(i64
Update @llvm.powi to handle different int sizes for the exponent This can be seen as a follow up to commit 0ee439b705e82a4fe20e2, that changed the second argument of __powidf2, __powisf2 and __powitf2 in compiler-rt from si_int to int. That was to align with how those runtimes are defined in libgcc. One thing that seem to have been missing in that patch was to make sure that the rest of LLVM also handle that the argument now depends on the size of int (not using the si_int machine mode for 32-bit). When using __builtin_powi for a target with 16-bit int clang crashed. And when emitting libcalls to those rtlib functions, typically when lowering @llvm.powi), the backend would always prepare the exponent argument as an i32 which caused miscompiles when the rtlib was compiled with 16-bit int. The solution used here is to use an overloaded type for the second argument in @llvm.powi. This way clang can use the "correct" type when lowering __builtin_powi, and then later when emitting the libcall it is assumed that the type used in @llvm.powi matches the rtlib function. One thing that needed some extra attention was that when vectorizing calls several passes did not support that several arguments could be overloaded in the intrinsics. This patch allows overload of a scalar operand by adding hasVectorInstrinsicOverloadedScalarOpd, with an entry for powi. Differential Revision: https://reviews.llvm.org/D99439
