779c775107 Make RSX MLB parser more resistant to bad files. 2022-06-13 22:54:47 +02:00

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.

7bbcbba5f5 Include undefined symbols in the symbol table for listing purposes. 
MACRO11 V05.05 does this:

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.

c4221e0b4b Sometimes pc-relative addressing needs no relocation record. 
In this case, in an absolute section refering to an absolute symbol.
Use test cases from Johnny Billquist.

e4ec481d3d Add RT11 macro libraries. 
Hopefully they won't open as RSX ones, because then they still won't work.
Can't test this now.

80b20b17eb Add some info about git commit when printing the version. 
Also modify dependency generation to be a side-effect of compilation.
It's still not quite perfect in picking up some changes (in particular
just after a commit, no files have changed but the git identification
is now different).

60d0afde00 Use the path search also for .INCLUDE, and add -I option: include path 
The -I option is used to specify the search path for .INCLUDE files.
It also appends this to the "INCLUDE" environment variable.

d38f4009c4 Crank up the warning levels, and adjust the code to silence ... 
several compilers:
- gcc version 4.5.3 (NetBSD nb2 20110806)
- gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13)
- Ubuntu clang version 3.6.0-2ubuntu1 (tags/RELEASE_360/final) (based on LLVM 3.6.0)

The warnings were mostly about local variables shadowing others,
unused function parameters, and C++ style comments. Some variables were
indeed used before set.

Note that on Linux, using -std=c99 does stupid things like *remove* the
declaration of strdup() from <string.h>. Therefore I've reluctantly used
-std=gnu99.

f75f5e1242 Change delimiters of local symbol blocks to be more like page 3-10 of the manual. 
Also, to make Kermit sources work, only increase the local symbol block
counter if there actually was a local symbol used in the block.
This way, conditional inclusions (which include source text only in the
first pass) will have less potential for de-synchronisation between the
passes. After all, if the generated internal local symbol names do
not match, phase errors will result (showing themselves as strange label
redefinition problems).

2c091595e9 Add option -yl1 to list pass 1 as well 
Normally listing is suppressed during the first pass, because there are
many unresolved symbols, which will be better in pass 2.
Errors are also suppressed because most of them are spurious.

With the -yl1 option, listing during pass 1 is not suppressed.
If you give the option twice, you also get the error messages.
