02b60ddd1c LEA: allow immediate syntax; ignore operand size entirely
The memory operand size of LEA doesn't matter in any way as it isn't
"real memory". Add an ANYSIZE option to ignore sizes entirely.

d13a6f9708 iflag.h: fix IF_CPU_LEVEL_MASK, add missing CPU definitions
Fix the definition of IF_CPU_LEVEL_MASK (which was missing the top
bit, IFM_ANY itself).

Add CPU definitions that we actually have into directiv.c.

c9cbd03dba iflag.h: simplify, fix iflag_cmp() when bit 31 is set
Additional simplifications, including using the new IFM_ masks,
and make IF_GENBIT() automatically mask the field number.

When bit 31 in a field is set, iflag_cmp() could return the wrong
ordering value. Fix.

418138c8f2 iflags: move definitions to a separate file; auto-generate more
Move the definitions to a separate file, in order to separate code
from data better.

We can auto-generate more information about the instruction flags, so
let's do so.

2e53f27e9d Move <string.h> inclusion to compiler.h
There is absolutely no reason not to include <string.h> globally, and
with the inline function for mempcpy() we need it there anyway.

99d45c850e Fix problem with C99 inlines and -Werror=missing-prototypes
Some older versions of gcc (gcc 4.2.1 at least) produce a warning,
promoted to error, on C99 inlines.  Do some work to figure out if we
need to fall back to GNU inline syntax.

Fix some issues with GNU inline syntax.

a7ecf2646d iflag: automatically assign values, saner handling of CPU levels
Automatically assign values to the instruction flags; we ended up with
a case where pushing flags into the next dword caused comparison
failures due to other places in the code explicitly comparing
field[3].

This creates necessary defines for this not to happen; it also cleans
up a fair bit of the iflag code.

This resolves BR 3392454.

0a126062fb ilog2(): inline functions if practical
For many (most?) targets these will be very small functions, so inline
them.  However, just in case make these external library functions.

b20bc733c9 asm/*: Move directive processing to its own file, refactor error handling
Move directive processing to its own file, and move nasmlib/error.c to
asm/error.c (it was not used by the disassembler); remove some extern
declarations from .c files, and do some general code cleanups.
