FileCheck [9/12]: Add support for matching formats
Summary:
This patch is part of a patch series to add support for FileCheck
numeric expressions. This specific patch adds support for selecting a
matching format to match a numeric value against (ie. decimal, hex lower
case letters or hex upper case letters).
This commit allows to select what format a numeric value should be
matched against. The following formats are supported: decimal value,
lower case hex value and upper case hex value. Matching formats impact
both the format of numeric value to be matched as well as the format of
accepted numbers in a definition with empty numeric expression
constraint.
Default for absence of format is decimal value unless the numeric
expression constraint is non null and use a variable in which case the
format is the one used to define that variable. Conclict of format in
case of several variable being used is diagnosed and forces the user to
select a matching format explicitely.
This commit also enables immediates in numeric expressions to be in any
radix known to StringRef's GetAsInteger method, except for legacy
numeric expressions (ie [[@LINE+<offset>]] which only support decimal
immediates.

The syntax to define a numeric variable is ``[[#<NUMVAR>:]]`` where

``<NUMVAR>`` is the name of the numeric variable to define to the matching

The syntax to define a numeric variable is ``[[#%<fmtspec>,<NUMVAR>:]]`` where:

* ``%<fmtspec>`` is an optional scanf-style matching format specifier to
|
||||
indicate what number format to match (e.g. hex number). Currently accepted
|

format specifiers are ``%u``, ``%x`` and ``%X``. If absent, the format
|
||||
specifier defaults to ``%u``.
|
||||
|
||||
* ``<NUMVAR>`` is the name of the numeric variable to define to the matching

value.

; CHECK: mov r[[#REG:]], 0x[[#%X,IMM:]]

would match ``mov r5, 0xF0F0`` and set ``REG`` to the value ``5`` and ``IMM``
|
||||
to the value ``0xF0F0``.

|
||||
* ``%<fmtspec>`` is the same matching format specifier as for defining numeric

variables but acting as a printf-style format to indicate how a numeric

expression value should be matched against. If absent, the format specifier
|

is inferred from the matching format of the numeric variable(s) used by the

expression constraint if any, and defaults to ``%u`` if no numeric variable

is used. In case of conflict between matching formats of several numeric

variables the format specifier is mandatory.
