preproc: add %i... variants, evaluated macro parameters, cleanups All directives which create single-line macros now have %i... variants to define case-insensitive versions. Case insensitive rather sucks, but at least this way it is consistent. Single-line macro parameters can now be evaluated as a number, as done by %assign. To do so, declare a parameter starting with =, for example: %define foo(x,=y) mov [x],macro_array_y ... would evaluate y as a number but leave x as a string. NOTE: it would arguably be better to have this as a per-instance basis, but it is easily handled by having a secondary macro called with the same argument twice. Finally, add a more consistent method for defining "magic" macros, which need to be evaluated at runtime. For now, it is only used by the special macros __FILE__, __LINE__, __BITS__, __PTR__, and __PASS__. __PTR__ is a new macro which evaluates to word, dword or qword matching the value of __BITS__. The magic macro framework, however, provides a natural hook for a future plug-in infrastructure to hook into a scripting language. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

preproc: standard macros now C-safe, %aliases off, fix %? recursion Enough users expect the namespace starting with underscore to be safe for symbols. Change our private namespace from __foo__ to __?foo?__. Use %defalias to provide backwards compatiblity (by using %defalias instead of %define, we handle the case properly where the user changes the value.) Add a preprocessor directive: %aliases off ... to disable all smacro aliases and thereby making the namespace clean. Finally, fix infinite recursion when seeing %? or %?? due to paste_tokens(). If we don't paste anything, the expansion is done. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

preproc: introduce alias smacros, cleanups Introduce "alias smacros", which are the smacro equivalent of symlinks; when used with the various smacro-defining and undefining directives, they affect the macro they are aliased to. Only explicit %defalias, %idefalias, and %undefalias affect them. This is intended for being able to rename macros while retaining the legacy names. This patch also removes an *astonishing* amount of duplicated code: 1. Every caller to defined_smacro() and undef_smacro() would call get_ctx() to mangle the macro name; push that into those functions. 2. Common code to get an smacro identifier. 3. Every code path that returns DIRECTIVE_FOUND also has to do free_tlist(origline); make it do so. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>

preproc: add support for builtin include modules (%use) Add a builtin equivalent to the %include directive called %use. %use includes a standard macro file compiled into the binary; these come from the macros/ directory in the source code. The idea here is to be able to provide optional macro packages with the distribution, without adding complex host filesystem dependencies.
