- 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.
I haven't done much compatibility testing with MACRO11 to check
weirdnesses, but the original functionality is very limied: none
of the mnemonics has operands.
which have an general (source) argument and an AC destination.
There are no FPP instrs which have 1 general source arg;
only with 1 general destination (even TSTF).
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.
Local symbols like 32768$ (and such long ones can be generated
automatically by macros) are suffixed with the "local symbol block number"
to make different labels in different local symbol blocks:
32768$12345.
However, this becomes longer than the regular symbol length (6).
So, to avoid changing these labels, they are not truncated at this length.
The listing code is updated to deal with the longest symbol name lengt
it encounters in the symbol table.
