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.

for pointers, etc.).

The zero-hexadecimal format has a representation similar to hexadecimal

but with padding zeroes to the left of the value. For example, a 32-bit

hexadecimal value of 0x1234 would be represented as 0x00001234 in the

zero-hexadecimal format.

For a variable with children, the format is set only on the

variable itself, and the children are not affected.
