# fe83270e	06-Sep-2018	Eric Christopher <[email protected]>	The initial .text section generated in object files was missing the 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 fin The initial .text section generated in object files was missing the 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.

# 52a7dd7d	15-Dec-2016	Prakhar Bahuguna <[email protected]>	[ARM] Implement execute-only support in CodeGen This implements execute-only support for ARM code generation, which prevents the compiler from generating data accesses to code sections. The followin [ARM] Implement execute-only support in CodeGen 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 show more ...
