9 years ago[AArch64] Improve TLS Descriptor pattern to release RTL loop IV opt
Jiong Wang [Thu, 6 Aug 2015 16:08:39 +0000 (16:08 +0000)]
[AArch64] Improve TLS Descriptor pattern to release RTL loop IV opt

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.

9 years agocompiler: Use context to determine types of complex expressions.
Ian Lance Taylor [Tue, 4 Aug 2015 22:27:48 +0000 (22:27 +0000)]
compiler: Use context to determine types of complex expressions.

    When determining the type of a complex expression, it is important
    to recognize cases where a complex value can be represented as a
    real number.

    Fixes golang/go#11572.

Ian Lance Taylor [Mon, 3 Aug 2015 18:23:42 +0000 (18:23 +0000)]
libgo/testsuite: kill sleep process in gotest

    This change modifies the "gotest" shell script
    to kill all processes, including "sleep", spawned
    by the timeout subshell. This prevents the sleep
    process from living beyond the gotest process.

    BACKGROUND

    The "gotest" shell script spawns "sleep" processes
    in the background to kill off test cases that run
    past their specified timeout. There are commands
    included that appear to kill the sleep process,
    but they only kill the parent shell, causing the
    sleep process to reparent.

    The orphaned sleep process can cause issues when
    gotest is run under some build systems, such as
    Ninja [0]. The particular issue with Ninja is the
    method it uses to identify terminated processes:
    it creates a pipe, passes the write end to the
    child process, and waits for EOF. In the case of
    libgo/gotest, the orphaned sleep process inherits
    the pipe FD and keeps it open for 4 minutes by
    default.
