dw2-case-insensitive.exp: p fuNC_lang fails on arm. The problem occurs
when thumb mode code is generated. On ARM last bit of function pointer
value indicates whether the target function is an ARM (if 0) or Thumb
(if 1) routine. The PC address should refer to actual address in
either case. This patch adds new compile unit and function labels to
code which act as address ranges of compile unit and functions in
debug information. Therefore address ranges will have correct
addresses and not the ones with an incremented least significant bit.
This patch has been tested on x86_64 and arm machines.
gdb/testsuite/ChangeLog:
2013-11-14 Omair Javaid <Omair.Javaid@linaro.org>
* gdb.dwarf2/dw2-case-insensitive-debug.S: Updated compile unit
and function label names.
* gdb.dwarf2/dw2-case-insensitive.c: Created function and
compile unit labels.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
* gdb.texinfo (Index Section Format): Change the version to 5.
Describe the different formula.
gdb/
Case insensitive lookups implementation.
* dwarf2read.c: Include ctype.h.
(struct mapped_index): New field version.
(mapped_index_string_hash): New parameter index_version. New comment
for it. Call tolower appropriately.
(find_slot_in_mapped_hash): New variable cmp, initialize it, use it.
Choose the right index version for mapped_index_string_hash.
(dwarf2_read_index): Support also the index version 5. Initialize the
new struct mapped_index field version.
(hash_strtab_entry): Pass INT_MAX for the new parameter, explain why.
(find_slot): Explain the version needs. Pass INT_MAX for the new
parameter.
(write_psymtabs_to_index): Produce version 5.
* minsyms.c (lookup_minimal_symbol): New variable cmp, initialize it,
use it. New comment for SYMBOL_MATCHES_SEARCH_NAME.
* psymtab.c (lookup_partial_symbol): Find the
SYMBOL_MATCHES_SEARCH_NAME start of the found block of matching
entries.
* symtab.c (lookup_symbol_in_language): Remove the case_sensitive_off
NAME lowercasing.
(search_symbols): Pass REG_ICASE to regcomp for case_sensitive_off.
(completion_list_add_name): New variable ncmp, initialize it, use it.
* symtab.h (SYMBOL_HASH_NEXT): Always call tolower.
* utils.c (strcmp_iw): Support case_sensitive_off.
(strcmp_iw_ordered): Sort in a way compatible with case_sensitive_off.
New function comment part. New variables saved_string1,
saved_string2 and case_pass. Add a proper second pass.
