2017-03-20RISC-V: Don't prefer FP_REGS for integersPalmer Dabbelt2-13/+6
On RISC-V we can't store integers in floating-point registers as this is forbidden by the ISA. We've always disallowed this, but we were setting the preferred mode to FP_REGS for some integer modes. This caused the LRA to blow up with some hard to read error messages. This patch removes the prefered mode hook, as the right thing to do here is nothing. Thanks to Kito for finding the bug, and mpf for the fix. See also <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79912>. PR target/79912 From-SVN: r246283
2017-03-20Use more conservative fences on RISC-VPalmer Dabbelt3-2/+9
The RISC-V memory model is still in the process of being formally specified, so for now we're going to be safe and add the I/O bits to userspace fences because there's no way to know if userspace is touching memory-mapped I/O regions at compile time. This will have no impact on existing microarchitecutres because they treat all fences conservatively. gcc/ChangeLog: 2017-03-17 Palmer Dabbelt <palmer@dabbelt.com> * config/riscv/riscv.c (riscv_print_operand): Use "fence iorw,ow". * config/riscv/sync.mc (mem_thread_fence_1): Use "fence iorw,iorw".
