Bill Schmidt d7802bf0dd This patch introduces initial-exec model support for thread-local storage ... on 64-bit PowerPC ELF. The patch includes code to handle external assembly and MC output with the integrated assembler. It intentionally does not support the "old" JIT. For the initial-exec TLS model, the ABI requires the following to calculate the address of external thread-local variable x: Code sequence Relocation Symbol ld 9,x@got@tprel(2) R_PPC64_GOT_TPREL16_DS x add 9,9,x@tls R_PPC64_TLS x The register 9 is arbitrary here. The linker will replace x@got@tprel with the offset relative to the thread pointer to the generated GOT entry for symbol x. It will replace x@tls with the thread-pointer register (13). The two test cases verify correct assembly output and relocation output as just described. PowerPC-specific selection node variants are added for the two instructions above: LD_GOT_TPREL and ADD_TLS. These are inserted when an initial-exec global variable is encountered by PPCTargetLowering::LowerGlobalTLSAddress(), and later lowered to machine instructions LDgotTPREL and ADD8TLS. LDgotTPREL is a pseudo that uses the same LDrs support added for medium code model's LDtocL, with a different relocation type. The rest of the processing is straightforward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169281 91177308-0d34-0410-b5e6-96231b3b80d8		2012-12-04 16:18:08 +00:00
