3eb7274625 Add some FP test cases, including some parse errors. 
Adjust the parsing a bit, and generate 0 values for bad syntax
like the reference version does.

3109f40bd5 Parse floats using integers (64 bits) only. 
The algorithm is close to what the reference version is doing.

ff183c0e36 Improve parsing of symbols. 
In particular, don't confuse `4..` with a symbol.

8d7414d7c3 Rename stream2 method "gets" to "getline" 
because FORTIFY re#defines gets, and this gets is something different.

c311f6a175 Release version 0.7.2 
since the current state seems stable.

39f1bcd238 Add %-expressions to CHANGES file. 2021-11-18 21:35:16 +01:00
Olaf Seibert
3a9d809b75 Optimize the previous version. 
Fold the functionality of pull_up_reg() into evaluate_rec().
pull_up_reg() essentially returned a flag (EX_REG at the top, or not)
which can be represented with the outgoing flags word.
The check for recursion depth is made unneeded by doing the
"exceptional" case outside the recursion; luckily it is actually the
common case.
 2021-11-15 21:35:37 +01:00
Olaf Seibert
1067b63043 Add the test with the weird expressions with registers. 
Now that we have some code that seems to do pretty much what we want.
 2021-11-15 19:28:19 +01:00

c29dc7d7af Work in progress... 
Make expressions work where the % operator isn't (only) at the top
level.
 2021-11-15 19:28:19 +01:00
Olaf Seibert
21e9410571 Add evaluation of %+unary expressions. 
This is a first step towards expressions like <%1>+1 and even later R1+1.

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.
 2021-05-30 13:19:39 +02:00
Olaf Seibert
652c047711 Better error message for .globl 1$ 
Local labels can't be exported (or imported).

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
Olaf Seibert
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.
