2018-12-21[ARM] Fix size-optimization-ieee testcase failureThomas Preud'homme4-0/+10
On some version of dejagnu, options in RUNTESTFLAGS are appended to the command-line and thus any -mfloat-abi=softfp or -mfloat-abi=hard in there overwrite the -mfloat-abi=soft in the dg-options for size-optimization-ieee-* tests. Test is still run though because arm_soft_ok returns true if -mfloat-abi=soft is accepted, even if the file is not compiled for softfloat due to a later -mfloat-abi on the command line. This patch adds a dg-skip-if to those tests to ensure they are not run in softfp or hard mode. 2018-12-21 Thomas Preud'homme <thomas.preudhomme@linaro.org> gcc/testsuite/ * gcc.target/arm/size-optimization-ieee-1.c: Skip if passing -mfloat-abi=softfp or -mfloat-abi=hard. * gcc.target/arm/size-optimization-ieee-2.c: Likewise. * gcc.target/arm/size-optimization-ieee-3.c: Likewise.

2018-12-19[ARM] Optimize executable size when using softfloat fmul/dmulThomas Preud'homme9-57/+214
Softfloat single precision and double precision floating-point multiplication routines in libgcc share some code with the floating-point division of their corresponding precision. As the code is structured now, this leads to *all* division code being pulled in an executable in softfloat mode even if only multiplication is performed. This patch create some new LIB1ASMFUNCS macros to also build files with just the multiplication and shared code as weak symbols. By putting these earlier in the static library, they can then be picked up when only multiplication is used and they are overriden by the global definition in the existing file containing both multiplication and division code when division is needed. The patch also removes changes made to the FUNC_START and ARM_FUNC_START macros in r218124 since the intent was to put multiplication and division code into their own section in a later patch to achieve the same size optimization. That approach relied on specific section layout to ensure multiplication and division were not too far from the shared bit of code in order to the branches to be within range. Due to lack of guarantee regarding section layout, in particular with all the possibility of linker scripts, this approach was chosen instead. This patch keeps the two testcases that were posted by Tony Wang on the mailing list to implement this approach and adds a new one. 2018-12-19 Thomas Preud'homme <thomas.preudhomme@linaro.org> libgcc/ * /config/arm/lib1funcs.S (FUNC_START): Remove unused sp_section parameter and corresponding code.

2018-12-19C++: better locations for bogus initializations (PR c++/88375)David Malcolm6-22/+114
PR c++/88375 reports that errors relating to invalid conversions in initializations are reported at unhelpfully vague locations, as in e.g.: enum struct a : int { one, two }; struct foo { int e1, e2; a e3; } arr[] = { { 1, 2, a::one }, { 3, a::two }, { 4, 5, a::two } }; for which g++ trunk emits the vague: pr88375.cc:12:1: error: cannot convert 'a' to 'int' in initialization 12 | }; | ^ with the error at the final closing brace. This patch uses location information for the initializers, converting the above to: pr88375.cc:10:11: error: cannot convert 'a' to 'int' in initialization 10 | { 3, a::two }, | ~~~^~~ | | | a highlighting which subexpression is problematic, and its type.

2018-12-19C++: improvements to binary operator diagnostics (PR c++/87504)David Malcolm19-76/+489
The C frontend is able (where expression locations are available) to print problems with binary operators in 3-location form, labelling the types of the expressions: arg_0 op arg_1 ~~~~~ ^~ ~~~~~ | | | arg1 type arg0 type The C++ frontend currently just shows the combined location: arg_0 op arg_1 ~~~~~~^~~~~~~~ and fails to highlight where the subexpressions are, or their types. This patch introduces a op_location_t struct for handling the above operator-location vs combined-location split, and a new class binary_op_rich_location for displaying the above, so that the C++ frontend is able to use the more detailed 3-location form for type mismatches in binary operators, and for -Wtautological-compare (where types are not displayed). Both forms can be seen in this example: bad-binary-ops.C:69:20: error: no match for 'operator&&' (operand types are 's' and 't') 69 | return ns_4::foo && ns_4::inner::bar; | ~~~~~~~~~ ^~ ~~~~~~~~~~~~~~~~ | | | | s t bad-binary-ops.C:69:20: note: candidate: 'operator&&(bool, bool)' <built-in> 69 | return ns_4::foo && ns_4::inner::bar; | ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~ The patch also allows for some uses of macros in -Wtautological-compare, where both sides of the comparison have been spelled the same way, e.g.: Wtautological-compare-ranges.c:23:11: warning: self-comparison always evaluates to true [-Wtautological-compare] 23 | if (FOO == FOO); | ^~ gcc/c-family/ChangeLog: PR c++/87504 * c-common.h (warn_tautological_cmp): Convert 1st param from location_t to const op_location_t &. * c-warn.c (find_array_ref_with_const_idx_r): Call fold_for_warn when testing for INTEGER_CST.

2018-12-19C++: more location wrapper nodes (PR c++/43064, PR c++/43486)David Malcolm47-214/+1309
This is v6 of the patch, as posted to: https://gcc.gnu.org/ml/gcc-patches/2018-12/msg01331.html The C++ frontend gained various location wrapper nodes in r256448 (GCC 8). That patch: https://gcc.gnu.org/ml/gcc-patches/2018-01/msg00799.html added wrapper nodes around all nodes with !CAN_HAVE_LOCATION_P for: * arguments at callsites, and for * typeid, alignof, sizeof, and offsetof. This is a followup to that patch, adding many more location wrappers to the C++ frontend. It adds location wrappers for nodes with !CAN_HAVE_LOCATION_P to: * all literal nodes (in cp_parser_primary_expression) * all id-expression nodes (in finish_id_expression), except within a decltype. * all mem-initializer nodes within a mem-initializer-list (in cp_parser_mem_initializer) However, the patch also adds some suppressions: regions in the parser for which wrapper nodes will not be created: * within a template-parameter-list or template-argument-list (in cp_parser_template_parameter_list and cp_parser_template_argument_list respectively), to avoid encoding the spelling location of the nodes in types. For example, "array<10>" and "array<10>" are the same type, despite the fact that the two different "10" tokens are spelled in different locations in the source. * within a gnu-style attribute (none of are handlers are set up to cope with location wrappers yet) * within various OpenMP clauses The patch enables various improvements to locations for bad initializations, for -Wchar-subscripts, and enables various other improvements in the followup patch. For example, given the followup buggy mem-initializer: class X { X() : bad(42), good(42) { } void* bad; int good; }; previously, our diagnostic was on the final close parenthesis of the mem-initializer-list, leaving it unclear where the problem is: t.cc: In constructor 'X::X()': t.cc:3:16: error: invalid conversion from 'int' to 'void*' [-fpermissive] 3 | good(42) | ^ | | | int whereas with the patch we highlight which expression is bogus: t.cc: In constructor 'X::X()': t.cc:2:13: error: invalid conversion from 'int' to 'void*' [-fpermissive] 2 | X() : bad(42), | ^~ | | | int Similarly, the diagnostic for this bogus initialization: i.cc:1:44: error: initializer-string for array of chars is too long [-fpermissive] 1 | char test[3][4] = { "ok", "too long", "ok" }; | ^ is improved by the patch so that it indicates which string is too long: i.cc:1:27: error: initializer-string for array of chars is too long [-fpermissive] 1 | char test[3][4] = { "ok", "too long", "ok" }; | ^~~~~~~~~~ gcc/c-family/ChangeLog: PR c++/43064 PR c++/43486 * c-common.c (unsafe_conversion_p): Fold any location wrapper.

2018-12-19[rs6000] Fix x86 SSSE3 compatibility implementations and testcasesPaul A. Clarke21-500/+443
This patch is the analog to r266868-r266870, but for SSSE3. The SSSE3 tests had been inadvertently made to PASS without actually running the test code. Actually running the code turned up some previously undetected issues. This patch fixes some issues in the implementations, fixes up the tests to use a union for the test data, which avoids strict aliasing issues, and enables the tests to actually run (by removing a dependency on __BUILTIN_CPU_SUPPORTS). Also, there's a fairly insignificant change in the testcases that walk through the data as pairs of vectors from: [0] and [1] [2] and [3] ... [n-4] and [n-3] [n-2] and [n-1] to: [0] and [1] [1] and [2] ... [n-3] and [n-2] [n-2] and [n-1] Since the testcases compute the correct answers based on the input, no other changes were necessary to effect the change. 2018-12-19 Paul A.
