Corinna Vinschen	09119463a1	stdio: split byte- and wide-char-oriented low-level output functions Introduce function __swbufw_r and macros/inline-functions called __swputc_r. Call these functions/macros exclusively from wide-char functions. This allows to set and test the stream orientation correctly even if output is only performed using byte-oriented macros from stdio.h.

Corinna Vinschen	61ccd3f94f	v{fs}printf/v{fs}wprintf: create external output helpers So far, the printf family of functions has two output helper functions called __sprint_r and __sfputs_r. Both are called from all variants of vfprintf as well as vfwprintf. There are also analogue helper functions for the string-creating functions vsprintf/vswprintf called __ssprint_r and __ssputs_r. However, the helpers are built once when building vfprintf/vsprintf with the INTEGER_ONLY flag, and then they are part of the vfiprintf.c and vsiprintf.c files. The problem is this: Even if a process only calls vfwprintf or the non-INTEGER_ONLY vfprintf it will always have to include the INTEGER_ONLY vfiprintf. Otherwise the helper functions are undefined. Analogue for the string-creating functions. That's a useless waste of space by including one (or two) big, unused function, if newlib is linked in statically. Create new files to define the printf output helpers separately and split them into byte-oriented and wide-char-oriented functions. This allows to link only the required functions. Also, simplify the string output helpers and fix a potential (but unlikely) buffer overflow in __ssprint_r. Fixes: `8a0efa53e4` ("import newlib-2000-02-17 snapshot") Fixes: `6121968b19` ("* libc/include/stdio.h (__VALIST): Guard against multiple definition.")

Mike Frysinger	96bc16f6b2	newlib: libc: merge build up a directory Convert all the libc/ subdir makes into the top-level Makefile. This allows us to build all of libc from the top Makefile without using any recursive make calls. This is faster and avoids the funky lib.a logic where we unpack subdir archives to repack into a single libc.a. The machine override logic is maintained though by way of Makefile include ordering, and source file accumulation in libc_a_SOURCES. There's a few dummy.c files that are no longer necessary since we aren't doing the lib.a accumulating, so punt them. The winsup code has been pulling the internal newlib ssp library out, but that doesn't exist anymore, so change that to pull the objects.	5 years ago
Mike Frysinger	fc2b4ffee0	newlib: libc: move manual into top-level build This doesn't migrate all the docs, just the libc's manual (pdf/info). This is to show the basic form of migrating the chew files. For subdirs that didn't have any docs, I've stripped their settings for clarity. If someone wanted to suddenly add docs, they can add the corresponding Makefile.inc files easily.	5 years ago
