[X86] Fix stack alignment for MCU target (Clang part), by Anton Nadolskiy. This patch fixes stack alignments for MCU (should be aligned to 4 bytes). Differential Revision: http://reviews.llvm.org/D15647 llvm-svn: 260376
2016-02-10 19:58:46 +08:00
// RUN: %clang_cc1 -triple i386-pc-elfiamcu -emit-llvm -o - %s | FileCheck %s
Reland "Change the X86 datalayout to add three address spaces for 32 bit signed, 32 bit unsigned, and 64 bit pointers." This reverts 57076d3199fc2b0af4a3736b7749dd5462cacda5. Original review at https://reviews.llvm.org/D64931. Review for added fix at https://reviews.llvm.org/D66843. llvm-svn: 371568

[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 `{{.*}} `.

Use functions with prototypes when appropriate; NFC A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); This is the eleventh batch of tests being updated (there are a significant number of other tests left to be updated).
