GDB has a workaround for DWARF output by ICC, related to missing DW_AT_declaration on incomplete types. The bug was fixed in ICC 14, so this commit adjusts GDB accordingly. For the version check, this adds a new parser function for the ICC producer string. While at it, it also adds unit tests for the producer parsing covering the new function and preexisting parsers. gdb/ChangeLog: 2017-09-26 Walfred Tedeschi <walfred.tedeschi@intel.com> Pedro Alves <palves@redhat.com> * dwarf2read.c (dwarf2_cu): Remove field producer_is_icc and add producer_is_icc_lt_14. (producer_is_icc_lt_14): New function. (check_producer): Add code for checking version of ICC. (producer_is_icc): Move to producer.c. (read_structure_type): Restrict ICC workaround to ICC<14. * producer.c: Include selftest.h. (producer_is_icc, producer_parsing_tests, _initialize_producer): New functions. * producer.h (producer_is_icc): New declaration.

Internal and external ICC versions have to be taken into account.

|
PRODUCER strings for internal releases are slightly different than
|
|
for public ones. Internal releases have a major release number and
|
|
0 as minor release. External releases have 4 fields, 3 of them are
|
|
not 0 and only two are of interest, major and update.
