d0089aef95 Fix bit-field truncation warning message 
Fix copy & paste bug with warning message.

struct X {
      signed int a : 3;
};
struct X g = { 5 };

Before:
s.c(4): Warning: Implicit truncation from 'int' to 'int : 3' in bit-field
initializer changes value from 5 to 5

After:
s.c(4): Warning: Implicit truncation from 'int' to 'int : 3' in bit-field
initializer changes value from 5 to -3

Fixes #1268

81ac28ff71 Used TAY/TYA instead of PHA/PLA when extracting a bit-field. 
Without optimization, it saves a few CPU cycles.  With optimization, it saves more cycles and a few bytes.

ea95728330 Avoided an avalanche of messages from bad bit-field declarations. 
Made cc65 replace a bad bit-field type with a good one, and always parse the field width.

Shortenned a parameter name to a spelling that's consistent with other function headers.

07ea5259ac Changed a cc65 error message to say that the sizes of bit-field types (not bit-fields) are limited. 2020-09-22 12:47:08 -04:00

41bd8d909b Added ld65's bank attribute to the cx16 library's bank (overlay) configuration file. 
That attribute makes it easier for Assembly code to know which bank holds a label.

0b64ca0d7d Fixed the ld65 cx16 Assembly configuration file. 
The CODE segment immediately follows the EXEHDR segment.  Added a segment for the zero-page area that's free when the BASIC ROM isn't used.

and new quick hack for tosshrax.

079f4a99dd Added processor state info to the OPCDesc table. However, since some opcodes are affected by the addressing mode, this info is unused in codegen/optimizer but just as quick in-code documentation/hints. 2020-09-18 09:04:15 +02:00
acqn
a7d6eb9190 Added processor flag usage/change-tracking for non-JSR/RTS code entries. 
Some existing optimizations are impacted and need fixes in order to work correctly again.
Fixed and improved OptPrecalc. Now it respects the C/V/Z/N flags.
Fixed optimizations impacted by added support of tracking processor flags.

ae6696fcb9 Removed some ambiguity from a statement. 
A limited number of bit-field types are required by the C standard, not by cc65.

ab7e9f8424 Hotfix for Issue #1250. 2020-09-08 16:28:21 +02:00

4e4e4c2d21 Allow char bit-fields 
These are not required to be supported (only int, signed int, and
unsigned int are required), but most compilers support it.

https://port70.net/~nsz/c/c89/c89-draft.html#3.5.2.1
https://port70.net/~nsz/c/c89/c89-draft.html#A.6.5.8

For consistency with other integral types, plain `char` bit-fields
are unsigned, regardless of the `--signed-chars` option.

Fixes #1047
