| /* GCC internal format strings consist of language frontend independent |
| format directives, implemented in gcc-4.3.0/gcc/pretty-print.c (function |
| pp_base_format), plus some frontend dependent extensions: |
| - for the C/ObjC frontend |
| in gcc-4.3.0/gcc/c-objc-common.c (function c_tree_printer) |
| - for the C++ frontend |
| in gcc-4.3.0/gcc/cp/error.c (function cp_printer) |
| Taking these together, GCC internal format strings are specified as follows. |
| |
| A directive |
| - starts with '%', |
| - either is finished by one of these: |
| - '%', '<', '>', "'", that need no argument, |
| - 'm', that needs no argument but looks at an err_no variable, |
| - or is continued like this: |
| - optionally 'm$' where m is a positive integer, |
| - optionally any number of flags: |
| 'q' (once only), |
| 'l' (up to twice) or 'w' (once only) (exclusive), |
| '+' (once only), |
| '#' (once only), |
| - finished by a specifier |
| |
| - 'c', that needs a character argument, |
| - 's', that needs a string argument, |
| - '.NNNs', where NNN is a nonempty digit sequence, that needs a |
| string argument, |
| - '.*NNN$s' where NNN is a positive integer and NNN = m - 1, that |
| needs a signed integer argument at position NNN and a string |
| argument, |
| - '.*s', that needs a signed integer argument and a string argument, |
| - 'i', 'd', that need a signed integer argument of the specified |
| size, |
| - 'o', 'u', 'x', that need an unsigned integer argument of the |
| specified size, |
| - 'p', that needs a 'void *' argument, |
| - 'H', that needs a 'location_t *' argument, |
| - 'J', that needs a general declaration argument, |
| - 'K', that needs a statement argument, |
| [see gcc/pretty-print.c] |
| |
| - 'D', that needs a general declaration argument, |
| - 'F', that needs a function declaration argument, |
| - 'T', that needs a type argument, |
| - 'E', that needs an expression argument, |
| [see gcc/c-objc-common.c and gcc/cp/error.c] |
| |
| - 'A', that needs a function argument list argument, |
| - 'C', that needs a tree code argument, |
| - 'L', that needs a language argument, |
| - 'O', that needs a binary operator argument, |
| - 'P', that needs a function parameter argument, |
| - 'Q', that needs an assignment operator argument, |
| - 'V', that needs a const/volatile qualifier argument. |
| [see gcc/cp/error.c] |
| |
| Numbered ('%m$' or '*m$') and unnumbered argument specifications cannot |
| be used in the same string. */ |
