[llvm-readobj] Change -t to --symbols in tests. NFC

2019-05-01T09:28:24+00:00

-t is --symbols in llvm-readobj but --section-details (unimplemented) in readelf. The confusing option should not be used since we aim for improving compatibility. Keep just one llvm-readobj -t use case in test/tools/llvm-readobj/symbols.test llvm-svn: 359661

[llvm-readobj] Change -long-option to --long-option in tests. NFC

2019-05-01T05:27:20+00:00

We use both -long-option and --long-option in tests. Switch to --long-option for consistency. In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf. While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf). llvm-svn: 359649

SHF_ARM_PURECODE flag when being built with the -mexecute-only flag. All code sections of an ELF must have the flag set for the final .text section to be execute-only, otherwise the flag gets removed. A HasData flag is added to MCSection to aid in the determination that the section is empty. A virtual setTargetSectionFlags is added to MCELFObjectTargetWriter to allow subclasses to set target specific section flags to be added to sections which we then use in the ARM backend to set SHF_ARM_PURECODE.

[CodeGen] Unify MBB reference format in both MIR and debug output

2017-12-04T17:18:51+00:00

As part of the unification of the debug format and the MIR format, print MBB references as '%bb.5'. The MIR printer prints the IR name of a MBB only for block definitions. * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)->getNumber\(\)/" << printMBBReference(*\1)/g' * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)\.getNumber\(\)/" << printMBBReference(\1)/g' * find . \( -name "*.txt" -o -name "*.s" -o -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#([0-9]+)/%bb.\1/g' * grep -nr 'BB#' and fix Differential Revision: https://reviews.llvm.org/D40422 llvm-svn: 319665

[ARM] Implement execute-only support in CodeGen

2016-12-15T07:59:08+00:00

This implements execute-only support for ARM code generation, which prevents the compiler from generating data accesses to code sections. The following changes are involved: * Add the CodeGen option "-arm-execute-only" to the ARM code generator. * Add the clang flag "-mexecute-only" as well as the GCC-compatible alias "-mpure-code" to enable this option. * When enabled, literal pools are replaced with MOVW/MOVT instructions, with VMOV used in addition for floating-point literals. As the MOVT instruction is required, execute-only support is only available in Thumb mode for targets supporting ARMv8-M baseline or Thumb2. * Jump tables are placed in data sections when in execute-only mode. * The execute-only text section is assigned section ID 0, and is marked as unreadable with the SHF_ARM_PURECODE flag with symbol 'y'. This also overrides selection of ELF sections for globals. llvm-svn: 289784

[MC] Don't use the architecture to govern which object file format to use

2015-12-22T01:39:04+00:00

InitMCObjectFileInfo was trying to override the triple in awkward ways. For example, a triple specifying COFF but not Windows was forced as ELF. This makes it easy for internal invariants to get violated, such as those which triggered PR25912. This fixes PR25912. llvm-svn: 256226

User may initialize a var with non-zero value and specify .bss section. E.g. : int a __attribute__((section(".bss"))) = 2; This patch converts an assertion to error report for better user experience. Differential Revision: http://reviews.llvm.org/D4199 llvm-svn: 211455
