2018-08-10Clarify source of tm.texi to copy for GFDL grantThomas Preud'homme2-1/+6
When tm.texi.in is updated in the source tree, the following message gets displayed: Verify that you have permission to grant a GFDL license for all new text in tm.texi, then copy it to <gcc src dir>/gcc/doc/tm.texi. Having been myself and some colleagues confused several time by that message as to what tm.texi to copy, I think it would be clearer to indicate the absolute path for the source as well.

2018-08-09Allow inner-loop reductions with variable-length vectorsRichard Sandiford4-0/+30
While working on PR 86871, I noticed we were being overly restrictive when handling variable-length vectors. For: for (i : ...) { res = ...; for (j : ...) res op= ...; a[i] = res; } we don't need a reduction operation (although we do for double reductions like: res = ...; for (i : ...) for (j : ...) res op= ...; a[i] = res; which must still be rejected). 2018-08-08 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-loop.c (vectorizable_reduction): Allow inner-loop reductions for variable-length vectors. gcc/testsuite/ * gcc.target/aarch64/sve/reduc_8.c: New test.

2018-08-09diagnostics: add line numbers to source (PR other/84889)David Malcolm15-10/+373
This patch adds a left margin to the lines of source (and annotations) printed by diagnostic_show_locus, so that e.g. rather than: test.c: In function 'test': test.c:12:15: error: 'struct foo' has no member named 'm_bar'; did you mean 'bar'? return ptr->m_bar; ^~~~~ bar we print: test.c: In function 'test': test.c:12:15: error: 'struct foo' has no member named 'm_bar'; did you mean 'bar'? 12 | return ptr->m_bar; | ^~~~~ | bar Similarly, for a multiline case (in C++ this time), this: bad-binary-ops.C: In function 'int test_2()': bad-binary-ops.C:26:4: error: no match for 'operator+' (operand types are 's' and 't') return (some_function () ~~~~~~~~~~~~~~~~ + some_other_function ()); ^~~~~~~~~~~~~~~~~~~~~~~~ becomes: bad-binary-ops.C: In function 'int test_2()': bad-binary-ops.C:26:4: error: no match for 'operator+' (operand types are 's' and 't') 25 | return (some_function () | ~~~~~~~~~~~~~~~~ 26 | + some_other_function ()); | ^~~~~~~~~~~~~~~~~~~~~~~~ I believe this slightly improves the readability of the output, in that it: - distinguishes between the user's source code vs the annotation lines that we're adding (the underlinings and fix-it hints here) - shows the line numbers in another place (potentially helpful for multiline diagnostics, where the user can see the line numbers directly, rather than have to figure them out relative to the caret: in the 2nd example, note how the diagnostic is reported at line 26, but the first line printed is actually line 25) I'm not sure that this is the precise format we want to go with [1], but I think it's an improvement over the status quo, and we're in stage 1 of gcc 9, so there's plenty of time to shake out issues. I've turned it on by default; it can be disabled via -fno-diagnostics-show-line-numbers (it's also turned off in the testsuite, to avoid breaking numerous existing test cases). [1] Some possible variants: - maybe just "LL|" rather than "LL | " - maybe ':' rather than '|' - maybe we should have some leading indentation, to better split up the diagnostics visually via the left-hand column - etc gcc/ChangeLog: PR other/84889 * common.opt (fdiagnostics-show-line-numbers): New option. * diagnostic-show-locus.c (class layout): Add fields "m_show_line_numbers_p" and "m_linenum_width"; (num_digits): New function.

2018-08-09Restore flow_bb_inside_loop_p tests (PR 86858)Richard Sandiford4-1/+28
The series to remove vinfo_for_stmt also removed tests of flow_bb_inside_loop_p if the call was simply testing whether the statement was in the vectorisation region. I'd tried to keep calls that were testing whether the statement was in a particular loop (inner or outer), but messed up in vect_is_simple_reduction and removed calls that were actually needed. This patch restores them. I double-checked the other removed calls and I think these are the only ones affected. 2018-08-08 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR tree-optimization/86858 * tree-vect-loop.c (vect_is_simple_reduction): Restore flow_bb_inside_loop_p calls. gcc/testsuite/ PR tree-optimization/86858 * gcc.dg/vect/pr86858.c: New test.

2018-08-08[libgomp, nvptx] Fall back to cuLinkAddData/cuLinkCreate if _v2 not foundTom de Vries3-4/+35
Cuda driver api functions cuLinkAddData and cuLinkCreate are available starting version 5.5. In version 6.5, they are remapped onto _v2 versions. The dlopen interface of the libgomp nvptx plugin uses the _v2 versions, so it won't work with a cuda driver with driver api version lower than 6.5. This patch fixes the problem by testing for the presence of the _v2 versions, and falling back to the original versions in case of absence of the _v2 versions. Build on x86_64 with nvptx accelerator and reg-tested libgomp, both with and without --without-cuda-driver. 2018-08-08 Tom de Vries <tdevries@suse.de> * plugin/cuda-lib.def (cuLinkAddData_v2, cuLinkCreate_v2): Declare using CUDA_ONE_CALL_MAYBE_NULL. * plugin/plugin-nvptx.c (cuLinkAddData, cuLinkCreate): Undef and declare.

This patch fixes that by: - defining CU_DEVICE_ATTRIBUTE_MAX_REGISTERS_PER_MULTIPROCESSOR to the hardcoded constant at toplevel, if not present in cuda.h, and - using CU_DEVICE_ATTRIBUTE_MAX_REGISTERS_PER_MULTIPROCESSOR in nvptx_open_device Build on x86_64 with nvptx accelerator and reg-tested libgomp. 2018-08-08 Tom de Vries <tdevries@suse.de> * plugin/plugin-nvptx.c (CU_DEVICE_ATTRIBUTE_MAX_REGISTERS_PER_MULTIPROCESSOR): Define.
