b931e65811 Fix ICE for bit-fields with typedef 
Fixes #1267

Avoid ICE, but treat plain int bit-fields declared via typedef as
signed rather than unsigned.  It is more efficient to treat them
as unsigned, but this requires distinguishing int from signed int,
and this is curently not done.

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.

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.

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
