[PATCH v2 0/2] Fix tab vs spaces in generated gdbarch.c

[Thiago Jung Bauermann <thiago.bauermann@linaro.org>]

Hello,

This version addresses Simon's review comments. It generates the same
gdbarch.c as v1. There are only minor formatting and code reorganization
changes in gdbarch.py.

Changes since v1:

- gdbarch.py: Fix indentation in the generated gdbarch_dump function
  - Formatted with black.
- gdbarch.py: Fix indentation in the generated set_gdbarch_* definitions
  - Formatted with black.
  - Added separate function to avoid duplicating the computation of the
    indentation characters, as proposed by Simon.

Original cover letter:

If you change gdbarch-components.py and submit a patch containing the
generated gdbarch.c file, git will point out that it contains whitespace
errors, e.g.:

Applying: gdb/aarch64: Detect vector length changes when debugging remotely
.git/rebase-apply/patch:164: indent with spaces.
                       "gdbarch_dump: update_architecture = <%s>\n",
.git/rebase-apply/patch:165: indent with spaces.
                       host_address_to_string (gdbarch->update_architecture));
.git/rebase-apply/patch:186: indent with spaces.
                                  gdbarch_update_architecture_ftype update_architecture)
warning: 3 lines add whitespace errors.

These patches make gdbarch.py generate indentation using tabs and spaces
as required by the GNU coding style. The first patch also takes the
opportunity to align the function arguments with the opening parenthesis
in the line above.

In both patches, “git show --ignore-all-space” confirms that gdbarch.c has
only whitespace changes.
