New page

== ISO C90 and ANSI C89 ==
Use --std-c89 to compile in this mode.

Not yet implemented in sdcc:
* Data type double.
* Structures and unions can not be assigned, passed as function parameters or return values.
* Diagnosis for qualifiers occuring multiple times in qualifier-specifier lists (sdcc always behaves according to the C99 standard in this respect).

Not yet implemented in some ports:
* Functions are not reentrant unless explicitly declared as such or --stack-auto is specified in the mcs51, hc08 and s08 ports.

== ISO C95 ==

Not yet implemented in sdcc:
* Data type double.
* Structures and unions can not be assigned, passed as function parameters or return values.
* Diagnosis for qualifiers occuring multiple times in qualifier-specifier lists (sdcc always behaves according to the C99 standard in this respect).

Not yet implemented in some ports:
* Functions are not reentrant unless explicitly declared as such or --stack-auto is specified in the mcs51, hc08 and s08 ports.

== ISO C99 ==
Use --std-c99 to compile in this mode.

Not yet implemented in sdcc:
* Data type double, long double.
* Structures and unions can not be assigned, passed as function parameters or return values.
* Intermingled declarations and code (variable declaration no longer restricted to file scope or the start of a compound statement (block)).
* Compound literals.
* Variable-length arrays.
* Integer constants and modulo for long long, unsigned long long, int_fast64_t, int_least64_t, int64_t, uint_fast64_t, uint_least64_t, uint64_t.
* Float classification macros in float.h.

Not yet implemented in some ports:
* Support for _Bool / bool is incomplete (no pointers to bool, or bool inside a struct) in the mcs51, ds390 and xa51 ports.
* Functions are not reentrant unless explicitly declared as such or --stack-auto is specified in the mcs51, hc08 and s08 ports.
* There is no support for data types long long, unsigned long long, int_fast64_t, int_least64_t, int64_t, uint_fast64_t, uint_least64_t, uint64_t in the mcs51, ds390, ds400, pic14, pic16 and xa51 ports.

== ISO C11 ==
Use --std-c11 to compile in this mode.

Not yet implemented in sdcc:
* Data type double, long double.
* Structures and unions can not be assigned, passed as function parameters or return values.
* Intermingled declarations and code (variable declaration no longer restricted to file scope or the start of a compound statement (block)).
* Compound literals.
* Integer constants and modulo for long long, unsigned long long, int_fast64_t, int_least64_t, int64_t, uint_fast64_t, uint_least64_t, uint64_t.
* Float classification macros in float.h (C11 requires more than C99).
* Alignment specification.
* Type-generic expressions.
* Improved Unicode support.
* gets_s().
* Static assertions.
* quick_exit().

Not yet implemented in some ports:
* Support for _Bool / bool is incomplete (no pointers to bool, or bool inside a struct) in the mcs51, ds390 and xa51 ports.

== Embedded C ==
While sdcc supports some of this standard's features (e.g. fixed-point math on the pic port, named address spaces in the mcs51 port) it does so in a way inconsistent with the standard.
Standard-compliant named address spaces are currently supported for bank-switching of data memory only.
