[PATCH v3 0/1] Fortran entry and DW_TAG_entry_point

[Nils-Christian Kempke]

Hi,

please find attached v3 of this series.

v1 can be found here:
https://sourceware.org/pipermail/gdb-patches/2022-March/186900.html

v2 can be found here:
https://sourceware.org/pipermail/gdb-patches/2022-April/187853.html

Since v2 I adapted the series to Tom's comment here
https://sourceware.org/pipermail/gdb-patches/2022-May/189479.html

Changes since v2:

  * In dwarf2/index-write.c (write_cooked_index): I added DW_TAG_entry_point
  to the GDB_INDEX_SYMBOL_KIND_FUNCTION when writing the GDB index.

  * In dwarf2/cooked-index.h (cooked_index_entry::matches): I added the
  DW_TAG_entry_point to the FUNCTIONS_DOMAIN which enabled me to break
  on entry points when compiled in a different CU than the one
  containing main (as was pointed out by Tom).

  * In testsuite/gdb.dwarf2/dw2-entry-points.exp: I added a second CU to
  the test DWARF containing an entry point which I used to test the
  changes in cooked-index.h

Cheers!
Nils
