Nick Kledzik	60db3549e2	[mach-o] enhance arm64 reloc parser to support local pointer relocations The arm64 assembler almost always uses r_extern=1 relocations in which the r_symbolnum field is the index of the symbol the relocation references. But sometimes it will set r_extern=0 in which case the linker needs to read the content of the reloction to determine the target. Add test case that the r_extern=0 relocation round trips. llvm-svn: 222198	2014-11-18 00:30:17 +00:00
Nick Kledzik	1bebb2832e	[mach-o] Add support for arm64 (AAarch64) Most of the changes are in the new file ArchHandler_arm64.cpp. But a few things had to be fixed to support 16KB pages (instead of 4KB) which iOS arm64 requires. In addition the StubInfo struct had to be expanded because arm64 uses two instruction (ADRP/LDR) to load a global which requires two relocations. The other mach-o arches just needed one relocation. llvm-svn: 217469	2014-09-09 23:52:59 +00:00

[mach-o] enhance arm64 reloc parser to support local pointer relocations

The arm64 assembler almost always uses r_extern=1 relocations in which the
r_symbolnum field is the index of the symbol the relocation references.  But
sometimes it will set r_extern=0 in which case the linker needs to read the
content of the reloction to determine the target.

Add test case that the r_extern=0 relocation round trips.

[mach-o] Add support for arm64 (AAarch64)

Most of the changes are in the new file ArchHandler_arm64.cpp.  But a few
things had to be fixed to support 16KB pages (instead of 4KB) which iOS arm64
requires.  In addition the StubInfo struct had to be expanded because
arm64 uses two instruction (ADRP/LDR) to load a global which requires two
relocations.  The other mach-o arches just needed one relocation.
