2020-06-03Revert "decl: Allow out-of-range enum constants when they don't change type"Michael Forney
This reverts commit 6229709b8ae21d7722fef48ad8a9f2f10b900030. I still don't understand how out-of-range enum constants are supposed to work.

2020-06-03decl: Allow out-of-range enum constants when they don't change typeMichael Forney
gcc and clang allow enum constants out of range of int, but this means that the type of enumerator may differ inside and outside the enum specifier. Instead, only allow out-of-range enum constants when their types are compatible with the final enum type.

2020-04-05expr: Just ignore decayed operand in unary `&` operatorMichael Forney
Reusing the decayed expression is more complicated, and only saved one malloc.
2020-04-04type: Remove unnecessary check for TYPEVOIDMichael Forney
There is only one type with this kind, so the equality check above suffices.
2020-04-04expr: Add type checking for equality and relational expressionsMichael Forney
2020-04-04expr: Fix type of '&' operator applied to arrayMichael Forney
It should be a pointer to the array, not to the first element (as it would after implicit conversion without the '&' operator).

2020-03-18expr: Slight simplification in function call parsingMichael Forney
2020-03-18pp: Remove some unnecessary conditionalsMichael Forney
It is fine to just pass NULL, or the result of malloc(0) to free().
2020-03-18pp: Fix possible use-after-freeMichael Forney
Restructure the loop slightly to avoid accessing the macro identifier token after we have checked for the open parenthesis; it might belong to a previous macro argument that has since been freed.

2020-03-18pp: Don't expand argument tokens if we don't need themMichael Forney

2020-03-17token: Add TOTHER for other non-whitespace tokensMichael Forney
This is for any non-whitespace character that doesn't match any other token categories, and could be valid if stringified, or the preprocessor is used by itself.
2020-03-17pp: Use tokencheck in a few more placesMichael Forney
2020-03-17pp: Fix some whitespace after preprocessingMichael Forney
2020-03-17pp: Add support for macro definition and expansionMichael Forney
The token pasting operator `##` still needs to be implemented.
2020-03-16scan: Keep track of whether tokens had preceeding whitespaceMichael Forney
2020-03-16token: Add tokencheck utility functionMichael Forney
This function is like expect(), but operates on a specific token and does not read the following token.

2020-03-16Allow multiple inputs to main compiler processMichael Forney
This way, we can implement -include in the driver by just passing an additional input to the compiler.
