Russell Joyce 7b43483f68
Added handling of "short int" type specifier 
Just consumes and discards the "int" token and treats as if it was only
a "short".
 2020-06-18 17:20:02 +01:00
Russell Joyce d04337125e
Added support for extern variable declarations 
Effectively just ignores any declarations as global scope is shared
across files in PicoC anyway, so the ultimate definition should be
enough.

Russell Joyce 5261facbd7
Fixed bug with typedef, introduced with extra type qualifier parsing 
Caused by overwriting the value of the actual type token being parsed by
any following tokens that were examined or consumed, rather than just
ignoring their values.

Russell Joyce 62969cb0ee
Added handling of 'const' type qualifier keyword 
There is currently no enforcement of a variable being constant, and the
actual type is the same as if 'const' wasn't present.

Russell Joyce 9fd31b6d37
Added handling of "long int" type specifier 
Just consumes and discards the "int" token and treats as if it was only
a "long".
 2020-06-10 18:24:12 +01:00
Russell Joyce b403e76600
Added handling of trailing type qualifiers/storage classes 
Handles situations such as `int volatile x` rather than `volatile int x`
by consuming the keywords as part of the type specifier.

Russell Joyce 45d85111f0
Added parsing of volatile qualifier 
This doesn't affect code execution, but is exposed through TypeParse().

value assigned to them. Part of #142

zik.saleeba 853b6f6259 Added some more comments. 
Added the beginnings of a debugger. It's not useful yet.

zik.saleeba e44b198946 Added a new alignment system which should correspond to the struct alignments of most processors. This means that picoc struct members should match up with native C structs in most cases. I hope.

Recognising and ignoring 'L' following integer constants.
Tallying the line count in multi-line C-style comments more correctly.

zik.saleeba e75518e139 Changed the way that arrays are represented to a simpler one without 
the extra level of indirection.
Fixed various array-related problems, including array assignment
which is issue #49.
