3c858fe45d Make sure immediate operands #R0 etc are output as absolute values. 
Previously it was generated as relocatable.

7f38f6ae03 Make it really easy to test putting undefined symbols in the main table. 2021-06-09 23:09:28 +02:00
Olaf Seibert
354aadfdc0 Add comment about undef'd symbols 
that they can also be put in the main symbol table, since all code is
made to work with that scenario.

d2d143dd9b Put undefined symbols in separate table. 
Even though all regression tests pass, it feels better to do the
undefined symbols similar to the implicit globals.

652c047711 Better error message for .globl 1$

0ab2a4fa16 Add consistency checking for symbol flags 
while also adding some consistency.
All listings now list . (dot) as defined so they need updating.
 2021-05-30 13:19:39 +02:00

7bbcbba5f5 Include undefined symbols in the symbol table for listing purposes.

cb8103d112 Run tests in both RSX11 and RT11 format. 
This is possible since our reference files are output from dumpobj,
and that does not depend on the format.

2753b081cc Start each pass with .DSABL LSB 
otherwise the end of pass 1 carries over into pass 2, which messes with
the ranges of local symbols.

22fdaedded Some floating point fixes. 
- Fixed immediate source operand of LDEXP, LD[IL][FD]
  which is an integer, unlike several other FPP instructions.
- Renamed floating point instruction formats so they match the
  instruction descriptions in the architecture handbook better.

b100021ffd Add check for odd branch target. 
Apart from the fact that instruction addresses must be even, this can't
even be expressed since the branch offset is expressed in words.
 2021-03-14 21:19:18 +01:00

0e373a8570 Make operand parsing error messages more helpful 
and add a test that is supposed to exercise them all.

7d4370af45 Make sure "str->stream.next = NULL" 
even though it isn't strictly necessary (stack_push() will set it
later).

54b73f7f9c Attempt bracketing checking. 
Too bad we can't issue a diagnostic here now; we just return failure
and the caller will probably next try a whitespace delimited string
next.
 2021-02-18 22:49:52 +01:00
Olaf Seibert
289860e539 Rearrange flow control in brackrange() 
which was a bit weird.
This also fixes a potential bug when a bracketed or nested string is not
properly terminated on this line.
