Ulrich Weigand a17a7e1868 [PowerPC] Rework TLS call operand processing ... As part of the global-dynamic and local-dynamic TLS sequences, we need to use a special form of the call instruction: bl __tls_get_addr(sym@tlsld) bl __tls_get_addr(sym@tlsgd) which generates two fixups. The current implementation of this causes problems with recognizing this form in the asm parser. To fix this, this patch reworks operand processing for this special form by using a single operand to hold both __tls_get_addr and sym@tlsld and defining a print method to output the above form, and an encoding method to generate the two fixups. As a side simplification, the patch replaces the two instruction patterns BL8_NOP_TLSGD and BL8_NOP_TLSLD by a single BL8_NOP_TLS, since the patterns already operate in an identical fashion (whether we have a local-dynamic or global-dynamic symbol is already encoded in the symbol modifier). No change in code generation intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185477 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-02 21:31:04 +00:00
