2015-08-06[AArch64] Improve TLS Descriptor pattern to release RTL loop IV optJiong Wang5-5/+75
The instruction sequences for preparing argument for TLS descriptor runtime resolver and the later function call to resolver can actually be hoisted out of the loop. Currently we can't because we have exposed the hard register X0 as destination of "set". While GCC's RTL data flow infrastructure will skip or do very conservative assumption when hard register involved in and thus some loop IV opportunities are missed. This patch add another "tlsdesc_small_pseudo_<mode>" pattern, and avoid expose x0 to gcc generic code. Generally, we define a new register class FIXED_R0 which only contains register 0, so the instruction sequences generated from the new add pattern is the same as tlsdesc_small_<mode>, while the operand 0 is wrapped as pseudo register that RTL IV opt can handle it. Ideally, we should allow operand 0 to be any pseudo register, but then we can't model the override of x0 caused by the function call which is hidded by the UNSPEC. So here, we restricting operand 0 to be x0, the override of x0 can be reflected to the gcc. 2015-08-06 Ramana Radhakrishnan <ramana.radhakrishnan@arm.com> Jiong Wang <jiong.wang@arm.com> gcc/ * config/aarch64/aarch64.d (tlsdesc_small_pseudo_<mode>): New pattern. * config/aarch64/aarch64.h (reg_class): New enumeration FIXED_REG0.
