2017-01-11[arm] Replace command-line option .def files with single definition fileRichard Earnshaw20-604/+4702
The files arm-cores.def, arm-fpus.def and arm-arches.def are parsed and used in several places and the format is slightly awkward to maintain as they must be parsable in C and by certain scripts. Furthermore, changes to the content that affects every entry is particularly awkward for dealing with merges. This patch replaces all three files with a single file that specifies all the command-line related definitions in a new format that allows for better checking for consistency as well as (hopefully) easier to merge changes. The awk script used to parse it is relatively complicated, but should be pretty portable. It works by parsing in all the data and then operating one of a number of possible sub-commands to generate the desired output. The new method picked up one error. The CPU descriptions referred to an architecture ARMv5tej which was not supported by -march. This has been fixed by adding the relevant entry to the architecture list. gcc: * config.gcc: Use new awk script to check CPU, FPU and architecture parameters for --with-... options. * config/arm/parsecpu.awk: New file * config/arm/arm-cpus.in: New file. * config/arm/arm-opts.h: Include arm-cpu.h instead of processing .def files. * config/arm/arm.c: Include arm-cpu-data.h instead of processing .def files. * config/arm/t-arm: Update dependency rules. * common/config/arm/arm-common.c: Include arm-cpu-cdata.h instead of processing .def files. * config/arm/genopt.sh: Deleted. * config/arm/gentune.sh: Deleted. * config/arm/arm-cores.def: Deleted. * config/arm/arm-arches.def: Deleted. * config/arm/arm-fpus.def: Deleted. * config/arm/arm-tune.md: Regenerated. * config/arm/arm-tables.opt: Regenerated. * config/arm/arm-cpu.h: New generated file. * config/arm/arm-cpu-data.h: New generated file. * config/arm/arm-cpu-cdata.h: New generated file.

2017-01-10Fix issues with unrepresentable column numbers (PR c++/77949)David Malcolm8-2/+84
PR c++/77949 identifies an ICE when the C++ frontend attempts to emit a fix-it hint inserting a missing semicolon at column 4097 of a source file. This column value exceeds LINE_MAP_MAX_COLUMN_NUMBER and hence isn't representable using a location_t. Attempting to do so leads to these problems, which this patch fixes: (a) when encountering a column number > LINE_MAP_MAX_COLUMN_NUMBER we create a new linemap with m_column_and_range_bits == 0, but linemap_position_for_column doesn't check for this, and hence can emit a bogus location_t value that's calculated relative to the previous linemap start, but which will be decoded relative to the new linemap, leading to very large incorrect line values. (b) when encountering a column number that can't be represented, and for which the linemap was pre-existing, the code would hit this assertion: if (linemap_assert_fails (column < (1u << map->m_column_and_range_bits))) around a bail-out condition. The patch replaces this assertion with a simple conditional, to stop the ICE when this occurs, and fixes the bit count (effective column bits, vs column+range bits) (c) the C++ frontend wasn't checking for failure of linemap_position_for_loc_and_offset when considering emitting the fix-it hint. The patch adds a conditional, so that no fix-it hint is emitted if the location is bogus. gcc/cp/ChangeLog: PR c++/77949 * parser.c (cp_parser_class_specifier_1): Only suggest inserting a missing semicolon if we have a valid insertion location for the fix-it hint. gcc/ChangeLog: PR c++/77949 * input.c (selftest::test_accessing_ordinary_linemaps): Verify that we correctly handle column numbers greater than LINE_MAP_MAX_COLUMN_NUMBER. gcc/testsuite/ChangeLog: PR c++/77949 * g++.dg/diagnostic/pr77949.C: New test case. libcpp/ChangeLog: PR c++/77949 * line-map.c (linemap_position_for_column): When calling linemap_start_line, detect if a new linemap was created with 0 column bits, and bail out early if this is the case.

To make this work, generate hash/equal functions for types that can use an identity comparison but are not a standard size and alignment. Drop the multiplications by 33 in the generated hash code and the reflect package hash code. They are not necessary since we started passing a seed value around, as the seed includes the hash of the earlier values.
