Simon Dardis	1dcb911061	[mips] Restrict tail call optimization ... The tail call optimization was being used without proper consideration of ABI requirements for saving and restoring the GP. This patch restricts tail call optimization to functions within the same translation unit.

Simon Dardis	d2ed8abb15	[mips] Disable tail calls temporarily ... Disable tail calls while the remaining bugs are fixed. Enable only for tests. Reviewers: vkalintiris Differential Review: https://reviews.llvm.org/D24912 llvm-svn: 282487	2016-09-27 13:15:54 +00:00
Simon Dardis	ea3431598e	[mips] Correct tail call encoding for MIPSR6 ... r277708 enabled tails calls for MIPS but used the 'jr' instruction when the jump target was held in a register. For MIPSR6, 'jalr $zero, $reg' should have been used. Additionally, add missing patterns for external and global symbols for tail calls.
