2018-01-26[AArch64] Fix gcc.target/aarch64/subs_compare_[12].cKyrylo Tkachov2-0/+45
This patch fixes the testsuite failures gcc.target/aarch64/subs_compare_1.c and subs_compare_2.c The tests check that we combine a sequence like: sub w2, w0, w1 cmp w0, w1 into subs w2, w0, w1 This is done by a couple of peepholes in aarch64.md. Unfortunately due to scheduling and other optimisations the SUB and CMP can come in a different order: cmp w0, w1 sub w0, w0, w1 And the existing peepholes cannot catch that and we fail to combine the two. This patch adds a peephole that matches the CMP as the first insn and the SUB as the second and outputs a SUBS. This is almost equivalent to the existing peephole that matches SUB first and CMP second except that it doesn't have the restriction that the output register of the SUB has to not be one of the input registers. Remember "sub w0, w0, w1 ; cmp w0, w1" is *not* equivalent to: "subs w0, w0, w1" but "cmp w0, w1 ; sub w0, w0, w1" is. So this is what this patch does. It adds a peephole for the case above and one for the SUB-immediate variant (because the SUB-immediate is represented as PLUS-of-negated-immediate and thus has different RTL structure). Bootstrapped and tested on aarch64-none-linux-gnu. * config/aarch64/aarch64.md: Add peepholes for CMP + SUB -> SUBS and CMP + SUB-immediate -> SUBS. From-SVN: r257102

2018-01-26[arm] XFAIL advsimd-intrinsics/vld1x2.cKyrylo Tkachov2-3/+16
This recently added test fails on arm. We haven't implemented these intrinsics for arm (any volunteers?) so for now let's XFAIL these on that target. Also, the float64 versions of these intrinsics are not supposed to be available on arm so this patch slightly adjusts the test to not include them for aarch32. In any case the entire test is XFAILed on arm, so this doesn't have any noticeable effect. The same number of tests (PASS) still occur on aarch64 but now they appear as XFAIL rather than FAIL on arm. * gcc.target/aarch64/advsimd-intrinsics/vld1x2.c: Make float64 tests specific to aarch64.

2018-01-26[ARC] Add JLI support.Claudiu Zissulescu15-81/+430
The ARCv2 ISA provides the JLI instruction, which is two-byte instructions that can be used to reduce code size in an application. To make use of it, we provide two new function attributes 'jli_always' and 'jli_fixed' which will force the compiler to call the indicated function using a jli_s instruction. The compiler also generates the entries in the JLI table for the case when we use 'jli_always' attribute. In the case of 'jli_fixed' the compiler assumes a fixed position of the function into JLI table. Thus, the user needs to provide an assembly file with the JLI table for the final link. This is usefully when we want to have a table in ROM and a second table in the RAM memory. The jli instruction usage can be also forced without the need to annotate the source code via '-mjli-always' command. gcc/ 2018-01-26 Claudiu Zissulescu <claziss@synopsys.com> John Eric Martin <John.Martin@emmicro-us.com> * config/arc/arc-protos.h: Add arc_is_jli_call_p proto. * config/arc/arc.c (_arc_jli_section): New struct.

2018-01-25compiler: look through aliases when looking for methodsIan Lance Taylor3-22/+49
Add a Type::is_alias method to remove some existing loops and avoid adding a new one. Test case is https://golang.org/cl/89935. Fixes golang/go#23489 Reviewed-on: https://go-review.googlesource.com/89975 From-SVN: r257069
2018-01-25compiler: deref receiver types in mangled namesIan Lance Taylor5-20/+24
This was the original intent, as reflected in the long comment at the start of names.cc, but I forgot to implement it. Also, remove a leading ".0" from the final name. That could occur for a method whose receiver type starts with 'u', as in that case we prepend a space to the mangled name, to avoid confusion with the Unicode mangling, and the space turns into ".0". Also, if the Unicode encoding would cause the final to start with "..u" or "..U", add a leading underscore. Patch gotest to not get fooled by some names. The result of these changes is that all symbols start with a letter or an underscore. Reviewed-on: https://go-review.googlesource.com/90015 From-SVN: r257068
2018-01-25jit: remove some unused fields from recording::union_ (PR jit/81672)David Malcolm2-4/+6
gcc::jit::recording::union_ has some stray fields, which are duplicates of those in the compound_type base class. It looks like these have been present since the initial merger of the jit branch to trunk (r217374), where it had three duplicate fields: location *m_loc; string *m_name; fields *m_fields; I removed the duplicate field "m_fields" in r219564 but missed the other two. This patch removes them. gcc/jit/ChangeLog: PR jit/81672 * jit-recording.h (gcc::jit::recording::union_): Remove fields "m_loc" and "m_name". From-SVN: r257066
