X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9450f09787cb78f72f67e199b706d84fd5011188;p=thirdparty%2Fbinutils-gdb.git

aarch64: Mark purecap object files with EF_AARCH64_CHERI_PURECAP

This simple patch sets the ELF header flag EF_AARCH64_CHERI_PURECAP for
purecap Morello object files, as documented in aaelf64-morello:
https://github.com/ARM-software/abi-aa/blob/main/aaelf64-morello/aaelf64-morello.rst

gas/ChangeLog:

2021-09-24  Alex Coplan  <alex.coplan@arm.com>

	* config/tc-aarch64.c (md_begin): Set the ELF header flag
	EF_AARCH64_CHERI_PURECAP if we have the C64 extension.
