Readme for language-c-0.10.0

[back to package description]

Language.C

Language.C is a parser and pretty-printer framework for C11 and the extensions of gcc.

See http://visq.github.io/language-c/

C Language Compatibility

Currently unsupported C11 constructs:

  • static assertion 6.7.10 (_Static_assert)
  • generic selection 6.5.1.1 (_Generic)
  • _Atomic, _Thread_local
  • Universal character names

Currently unsupported GNU C extensions:

  • __auto_type
  • __builtin_offsetof char a[__builtin_offsetof (struct S, sa->f)
  • _Decimal32
  • Extended assembler __asm__ __volatile__ ("" : : : ); __asm__ goto ("" : : : : label);
  • __attribute__((packed)): types featuring this attribute may have an incorrect size or alignment calculated.

IEC 60559:

Since language-c-0.8, extended floating point types are supported (gcc 7 feature). Package maintainers may decide to disable these types (flag iecFpExtension) to work around the fact that the _Float128 type is redefined by glibc >= 2.26 if gcc < 7 is used for preprocessing:

  /* The type _Float128 exists only since GCC 7.0.  */
  # if !__GNUC_PREREQ (7, 0) || defined __cplusplus
  typedef __float128 _Float128;
  # endif

Examples

A couple of small examples are available in examples.
