744facb7fc * properly support accepting register parameters of assembler routines in 
the intel assembler reader: no longer parse them as register tokens,
    but as local operands that are later converted into registers. This
    ensures in particular that the type of the operand is set, which is
    necessary in case this operand later subscripted (as in tasm10a)

61af0fb72d * only take into account the location of the parameter at the callee side to 
determine whether it's in a register if it's a pure assembler routine
  * you can't "index" implicit pointers either using their fields

aa82e00615 * fixed check to determine whether a record parameter can be subscripted 
directly in inline assembly: that's only possible if it's a register
    parameter where the address of the record was passed (rather than the
    record itself), or if a parameter has been explicitly typecasted in
    Intel-style assembly using ".size"

8ae0864c9a * x86 Intel asm reader: handle special variables "self" and "result" similar to regular ones in terms of subscripting. This makes fix from r34911 apply to these special variables. Resolves #31542.

d5ffc2da97 * Force OPR_LOCAL operand into reference whenever subscripting is used, so that all record fields are handled in same way regardless of their offset. Previously, operand was changed to reference only by fields with non-zero offset (see logic in tcgasmnode.ResolveRef method).

aa1be3276f - removed default value of _typ parameter of TAsmData.(Weak)RefAsmSymbol():

f69f6336e9 * Replaced hacks with resetting 'c' to zero and decreasing inputpointer by boolean parameter to skipcomment and skipoldtpcomment. This parameter specifies whether first character of comment should be read.

bbfbab7e0c * Moved handling of comments and line breaks in assembler blocks from scanner to tokenizer level. Handling them at character level was causing compiler to accept comments in the middle of any assembler token, which should never happen. It was also causing Mantis #27459: a newline immediately after closing 'end' token was first handled in asmgetchar and then by normal parser, causing all subsequent line numbering to be off by one.

the i8086, as 'near' and 'far' actually work there. Some forms may even work

  there on i386 and x86_64.

case a record contains an internal typed constant of its own type
    (which happened becuase such a typed constant is also fieldvarsym, solved
     by checking for sp_static) (mantis #27880)

    interested in instance fields, but processed all fieldvarsyms

42d251da1c - x86 assembler readers: cleaned out operand swapping code. Operands of TInstruction are kept in AT&T order, Intel reader attaches operands right-to-left. It was effectively the same way before the change (except Intel reader attaching operands left-to-right, followed by a single swap), operand order checks all over the place were just reducing readability.

b6bfa864d4 Disallow the usage of the inline assembler inside generics, because there are currently two problems: 
1. At least on x86 the assembler reader initializes the parameter location informations which results in InternalError 200301231
2. Assembler tokens are not stored in the token stream and thus won't be reproduced during specialization

x86/rax86int.pas, tx86intreader.Assemble:
  * check for "parse_generic" before calling generate_parameter_info
pstatmnt.pas, assembler_block & statement:
  * generate an error message if an asm statement should be parsed inside a generic
