Proper use of bool and enum makes code easier to debug. Do more of
it. In particular, we really should stomp out any residual uses of
magic constants that aren't enums or, in some cases, even #defines.
Both C and C++ have "bool", "true" and "false" in lower case; C
requires <stdbool.h> for this, in C++ it is an inherent type built
into the compiler. Use those instead of the old macros; emulate with
a simple typedef enum if unavailable.
SAA's were never intended to allow random access, but several backends
do random or semirandom access via saa_fread() and saa_fwrite()
anyway. Rewrite the SAA system to allow for efficient random access.
On "label.pl 10000000" this improves performance by a factor of 12.
Concentrate compiler dependencies to compiler.h; make sure compiler.h
is included first in every .c file (since some prototypes may depend
on the presence of feature request macros.)
Actually use the conditional inclusion of various functions (totally
broken in previous releases.)
Add nasm_zalloc(), a wrapper around calloc(), to allocate
zero-initialized memory. For large allocations, this is often far
more efficient than allocating and zeroing, since the operating system
tends to keep a pool of zero pages around.
Finish the perfect hash tokenizer, and actually enable it.
Move stdscan() et al to a separate file, since it's not needed in any
of the clients of nasmlib other than nasm itself.
Run make alldeps.
- MOV gpr,CRx or MOV CRx,gpr can access high control registers with a LOCK
prefix; handle that in both the assembler and disassembler.
- Get a saner error message when trying to access high resources in
non-64-bit mode.
