varobj zero-padded hexadecimal format
This set of patches add support for the zero-padded hexadecimal format for
varobj's, defined as "zero-hexadecimal". We currently only support regular
non-zero-padded hexadecimal.
Talking with IDE developers, they would like to have this option that is
already available to GDB's print/x commands, in the CLI, as 'z'.
gdb/ChangeLog:
2015-12-09 Luis Machado <lgustavo@codesourcery.com>
* gdb/mi/mi-cmd-var.c (mi_parse_format): Handle new "zero-hexadecimal"
format.
* gdb/varobj.c (varobj_format_string): Add "zero-hexadecimal" entry.
(format_code): Add 'z' entry.
(varobj_set_display_format): Handle FORMAT_ZHEXADECIMAL.
* gdb/varobj.h (varobj_display_formats) <FORMAT_ZHEXADECIMAL>: New enum
field.
* NEWS: Add new note to MI changes citing the new zero-hexadecimal
format for -var-set-format.
gdb/doc/ChangeLog:
2015-12-09 Luis Machado <lgustavo@codesourcery.com>
* gdb.texinfo (GDB/MI Variable Objects): Update text to mention
-var-set-format's new zero-hexadecimal format.
gdb/testsuite/ChangeLog:
2015-12-09 Luis Machado <lgustavo@codesourcery.com>
* gdb.mi/mi-var-display.exp: Add new checks for the zero-hexadecimal
format and change test names to make them unique.
