* Add assembly support for -fsanitize=hwaddress tagged globals.Peter Collingbourne2019-08-22
| | | | | | | | | | | | | | | | | As of LLVM r368102, Clang will set a pointer tag in bits 56-63 of the address of a global when compiling with -fsanitize=hwaddress. This requires an adjustment to assembly code that takes the address of such globals: the code cannot use the regular R_AARCH64_ADR_PREL_PG_HI21 relocation to refer to the global, since the tag would take the address out of range. Instead, the code must use the non-checking (_NC) variant of the relocation (the link-time check is substituted by a runtime check). This change makes the necessary adjustment in the movrel macro, where it is needed when compiling with -fsanitize=hwaddress.

| * arm: Create proper .rdata sections for COFFMartin Storsjö2019-01-25
| | | | | | | | | | | | | | | | | | | | | | | | As .rodata isn't one of the default created sections for COFF, it was created as a read-write data section. By using the default .rdata section name for COFF, it automatically becomes a read-only data section. The existing ".section .rodata" works as intended for ELF though. This is based on an original patch and diagnose by Tom Tan <Tom.Tan@microsoft.com>. Signed-off-by: Martin Storsjö <martin@martin.st>

| * aarch64: Fix negative movrel offsets for windowsMartin Storsjö2017-08-22
| | | | | | | | | | | | | | | | | | On windows, the offset for the relocation doesn't get stored in the relocation itself, but as an unsigned immediate in the opcode. Therefore, negative offsets has to be handled via a separate sub instruction, just as on MachO. Signed-off-by: Martin Storsjö <martin@martin.st>
