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: deref receiver types in mangled namesIan Lance Taylor3-18/+22
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

These testcases jit-compile functions that return char, but were erroneously calling them as if they returned int. This led to errors for certain target configurations (e.g. reading from %eax (32-bit) in the harness when only %al (8-bit) had been written to in the jit-compiled function). gcc/testsuite/ChangeLog: PR jit/82846 * jit.dg/test-alignment.c (create_aligned_code): Fix return type of "fn_type" typedef. * jit.dg/test-alignment.cc (verify_aligned_code): Likewise.

2018-01-24compiler: rationalize external symbol namesIan Lance Taylor13-352/+899
Encode all external symbol names using only ASCII alphanumeric characters, underscore, and dot. Use a scheme that can be reliably demangled to a somewhat readable version as described in the long comment in names.cc. A minor cleanup discovered during this was that we were treating function types as different if one had a NULL parameters_ field and another has a non-NULL parameters_ field that has no parameters. This worked because we mangled them slightly differently. We now mangle them the same, so we treat them as equal, as we should anyhow.

2018-01-24Fix m68k-linux-gnu libgcc build for ColdFire (PR target/68467).Joseph Myers2-0/+27
PR target/68467 is libgcc failing to build for m68k-linux-gnu configured for ColdFire. Jeff has an analysis in the PR identifying the problem as resulting from the callers of libcalls with 1-byte or 2-byte arguments wanting to push just 1 or 2 bytes on the stack, while the libcall implementations have the normal C ABI and expect 4-byte arguments. For normal C functions, I believe the TARGET_PROMOTE_PROTOTYPES definition would ensure such arguments get passed as 4-byte, but that does not apply for libcalls. This patch fixes the issue by defining TARGET_PROMOTE_FUNCTION_MODE for m68k. The definition is conservative, only applying promotions in the case of arguments to libcalls; otherwise it returns the unpromoted type, which I believe matches what the default implementation of the hook would have done on m68k. I have tested that this fixes the libgcc build for ColdFire, and, in conjunction with one glibc patch, this enables glibc to build cleanly for ColdFire and to pass the compilation parts of the glibc testsuite except for one test unrelated to this patch (while glibc and the compilation parts of the testsuite continue to build OK for non-ColdFire m68k, as expected). I have *not* run any GCC tests for this patch, or any execution tests for m68k. PR target/68467 * config/m68k/m68k.c (m68k_promote_function_mode): New function.

2018-01-24Remove explicit dg-do runs from gcc.dg/vect (PR 83889)Richard Sandiford22-30/+30
The failures in this PR were from forcing { dg-do run } even when vect.exp chooses options that are incompatible with the runtime. The default vect.exp behaviour is to execute when possible, so there's no need for a dg-do at all. The patch removes other unconditional { dg-do run }s too. Many of them were already failing in the same way. Also, the dg-do run condition in vect-reduc-or* seems unnecessary: the test should run correctly whatever happens, and the scan tests are already guarded properly. 2018-01-24 Richard Sandiford <richard.sandiford@linaro.org> gcc/testsuite/ PR testsuite/83889 * gcc.dg/vect/pr79920.c: Remove explicit dg-do run. * gcc.dg/vect/pr80631-1.c: Likewise. * gcc.dg/vect/pr80631-2.c: Likewise. * gcc.dg/vect/pr81410.c: Likewise. * gcc.dg/vect/pr81633.c: Likewise. * gcc.dg/vect/pr81815.c: Likewise. * gcc.dg/vect/pr82108.c: Likewise. * gcc.dg/vect/pr83857.c: Likewise. * gcc.dg/vect/vect-alias-check-8.c: Likewise. * gcc.dg/vect/vect-alias-check-9.c: Likewise. * gcc.dg/vect/vect-alias-check-10.c: Likewise. * gcc.dg/vect/vect-alias-check-11.c: Likewise. * gcc.dg/vect/vect-alias-check-12.c: Likewise. * gcc.dg/vect/vect-reduc-11.c: Likewise. * gcc.dg/vect/vect-tail-nomask-1.c: Likewise. * gcc.dg/vect/vect-reduc-in-order-1.c: Remove dg-do run and use dg-xfail-run-if instead. * gcc.dg/vect/vect-reduc-in-order-2.c: Likewise. * gcc.dg/vect/vect-reduc-in-order-3.c: Likewise. * gcc.dg/vect/vect-reduc-in-order-4.c: Likewise. * gcc.dg/vect/vect-reduc-or_1.c: Remove conditional dg-do run. * gcc.dg/vect/vect-reduc-or_2.c: Likewise.

2018-01-24[testsuite] Fix arm options in gcc.dg/lto/20110201-1_0.cKyrylo Tkachov2-1/+7
This test fails on arm hardfloat targets because it sets an explicit -mfloat-abi=softfp. The usual approach to setting the NEON options is to use dg-add-options arm_neon. But in the lto tests we don't have that framework, we can only set them explicitly with dg-lto-options. The solution is to remove the explicit -mfloat-abi=softfp and instead add an effective target check for arm_neon_ok_no_float_abi that makes sure we only run this test if -mfpu=neon is enough to get NEON without any -mfloat-abi options. In fact, this is what the comment above check_effective_target_arm_neon_ok_no_float_abi_nocache recommends for lto tests. That way on my hardfloat toolchain the test doesn't try to link the softfp binary against a hard-float runtime/test glue and all is good. I've tested that the test is appropriately skipped when testing a --with-float=soft toolchain. * gcc.dg/lto/20110201-1_0.c: Remove explicit -mfloat-abi=softfp option. Add arm_neon_ok_no_float_abi check. From-SVN: r257017
