BR3066383: Restore backward compatibility with token pasting
It seems to be a bit long story for the reason if this bug. But
lets be verbose and describe all byte-to-byte. And it is all about
preprocessor code, in particular paste_tokens and expand_mmac_params.
Initially the problem (not the same but similar) was noticed and
fixed in commit
ec88c1be. The problem reveals itself with code snippets
like
| %macro m 1
| %push
| %define %$arg %1
| %%top_%$arg:
| resb ($ - %%top_%$arg)
| %pop
| %endmacro
So with commits
ec88c1be,
51fd86e0,
1f6741fc,
985d880c we did expand
local single macro before processing tokens pasting unconditionally.
But then it being found that such approach breaks %assign directive.
The snippets like below didn't work
| %macro m 1
| %push
| %assign %$arg %1
| %assign %$arg %1+%$arg
| %pop
| %endmacro
So all these commits were reverted and we just stop pasting tokens
in paste_tokens() after TOK_PREPROC_ID (commit
20a94ad7). Unfortunately
this breaks %assign with compound preproc id
| %macro m3 1
| %push
| %assign %$_uses 0
| %rep 4
| %assign %$_ur%$_uses %$_uses
| mov ecx, %$_ur%$_uses
| %assign %$_uses %$_uses+1
| %endrep
| %pop
| %endmacro
To fix this bug we have to combine two approaches at once,
we should continue pasting after TOK_PREPROC_ID and expand
sequential TOK_PREPROC_IDs except first one.

nasm.h: move "regs.h" to top; make is_register() a bool
Move the #include of regs.h to the top with the other includes, and
make is_register() -- being a boolean predicate -- return bool.

move is_register helper to nasm.h
H. Peter Anvin noted:
|
| Could we avoid putting static code that has no dynamic content in
| dynamically generated files... it just complicates things unnecessarily.
|
| The above can move into nasm.h for example.

Good idea.

Improve process_ea and introduce -OL
Two fixes:
1. Optimization of [bx+0xFFFF] etc
0xFFFF is an sbyte under 16-bit semantics,
so make sure to check it right.
2. Don't optimize displacements in -O0
Displacements that fit into an sbyte or
can be removed should *not* be optimized in -O0.
Implicit zero displacements are still optimized, e.g.:
[eax] -> 0 bit displacement, [ebp] -> 8 bit displacement.
However explicit displacements are not optimized:
[eax+0] -> 32 bit displacement, [ebp+0] -> 32 bit displacement.
Because #2 breaks compatibility with 0.98,
I introduced a new optimization level: -OL, legacy.
