Fix volatile _Complex alignment test on platforms where 64-bit floating point isn't 64-bit aligned Add x86-64 triple, and check its datalayout. Also add some comments, and use the new CHECK-LABEL. llvm-svn: 186564
2013-07-18 14:11:45 +08:00
// RUN: %clang_cc1 -triple x86_64-unknown-unknown -emit-llvm %s -o - | FileCheck %s
// Validate that volatile _Complex loads and stores are generated
// properly, including their alignment (even when overaligned).
//
// This test assumes that floats are 32-bit aligned and doubles are
// 64-bit aligned, and uses x86-64 as a target that should have this
Misc test cleanups. * tbaa-struct.cpp always has a 64 bit pointer. * f32:32:32, f64:64:64 and f128:128:128 are defaults, don't assume they are printed. llvm-svn: 197415

Propagate alignment for _Complex _Complex load/store didn't have their alignment set properly, which was visible when GCC's torture tests use volatile _Complex. Update some existing tests to check for alignment, and add a new test which also has over-aligned volatile _Complex (since the imaginary part shouldn't be overaligned, only the real part). llvm-svn: 186490

[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 `{{.*}} `.
