2012-12-14This patch removes some nondeterminism from direct object file outputBill Schmidt
for TLS dynamic models on 64-bit PowerPC ELF. The default sort routine for relocations only sorts on the r_offset field; but with TLS, there can be two relocations with the same r_offset. For PowerPC, this patch sorts secondarily on descending r_type, which matches the behavior expected by the linker. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170237 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-12The ordering of two relocations on the same instruction is apparently notBill Schmidt
predictable when compiled on at least one non-PowerPC host. Source of nondeterminism not apparent. Restrict the test to build on PowerPC hosts for now while looking into the issue further. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170016 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-12This patch implements local-dynamic TLS model support for the 64-bitBill Schmidt
PowerPC target. This is the last of the four models, so we now have full TLS support. This is mostly a straightforward extension of the general dynamic model. I had to use an additional Chain operand to tie ADDIS_DTPREL_HA to the register copy following ADDI_TLSLD_L; otherwise everything above the ADDIS_DTPREL_HA appeared dead and was removed. As before, there are new test cases to test the assembly generation, and the relocations output during integrated assembly. The expected code gen sequence can be read in test/CodeGen/PowerPC/tls-ld.ll. There are a couple of things I think can be done more efficiently in the overall TLS code, so there will likely be a clean-up patch forthcoming; but for now I want to be sure the functionality is in place.
