Semi-arbitrary change of the definition of escp to the beginning of
the argument sequence instead of the initiator character. This may
avoid an add in some code paths, and looks slightly cleaner to me.
We used numbers in nasm_unquote and C escapes in nasm_quote - use
numbers in both places, just in case some C compiler does something
weird with '\r' and (especially) '\n'.
Make the code a bit more consistent:
- ndig is now always a countdown, and we always to the (p > escp+1)
test to see if we got anything at all (this is to deal with stuff
like \x without a digit.)
- Add missing break; after 'v' (bug!).
- Preinitialize nval to zero.
Greatly simplify nasm_skip_string() by observing that for the purpose
of string skipping, all states other than st_backslash are equivalent
to st_start.
ASCII specifically refers to characters <= 127, so to use "ASCII" for
literal bytes is really confusing in a multibyte environment. Give an
example of using Unicode escapes.
Move all the date/time macros to a common section so we can give a
common example. We don't have support for a fourth level of headers,
so just use a bulleted list.
Introduce new preprocessor directives %depend and %pathsearch, and
make incbin a standard macro using these filenames. This lets us
remove the code that makes incbin search the path.
Call expand_smacros() early instead of expand_smacros_in_string()
late. expand_smacros_in_string() seems like a prodigiously bad idea
and a sheer brainfart in my opinion.
Add the -MP option to emit phony targets. Since this means each
header file has to be visited more than once, change the
implementation to use an internal list of all the dependencies, and
centralize the emission of the dependency files.
Implement the dependency options:
-MF: set the file to which dependencies are written.
-MD: generate dependencies in parallel with compilation.
-MT: set the name of the dependency target.
-MQ: same as -MT, but *attempt* to quote it for Makefile safety.
struct hash_table, a fixed-sized structure, is now allocated by the
caller. This lets us integrate it into the Context structure, thus
avoiding an additional dynamically allocated object for no good
reason.
Add some minor code collapsing: make it more obvious that all that
differs is a pointer value, rather than relying on the compiler to do
tail merging.
BR 1974170: VCVTPD2PS, VCVTPD2DQ, VCVTTPD2DQ with a memory operand are
ambiguous without a specific operand size, so force one to be added.
Split the instruction pattern due to our current clunky handling of
MMX/XMM/YMM registers together with sizes. Fix in the future, please!
