7d05f741e7 Merge "Have stdatomic.h punt to C++ atomic when possible" 2014-08-15 05:01:31 +00:00
Hans Boehm
019d395811 Have stdatomic.h punt to C++ atomic when possible 
This is an alternate, somewhat simpler, fix that makes it safe to
include both <atomic> and <stdatomic.h> from C++ code in either order.
It means that C code consistently uses one implementation of atomics
and C++ another.  We still have to make sure that those two
implementations interoperate correctly at runtime; in particular,
any flavor of atomic object needs to be represented exactly like the
underlying type, with the proper alignment constraint.

1467dfe3e8 Make string tests check all alignment combinations 
Reduce randomization of the test by (1) replacing random() & 255
 with hard-coded char and (2) by making State *Iteration function
 visit every possible alignment combination instead of 10 random ones.

bafee43161 Change name of MB_CUR_MAX implementation function. 
Glibc calls theirs __ctype_get_mb_cur_max. Make ours match to cut down
on differences between bionic and glibc.

76212eeb53 Add more functionality to glibc symbol checker. 
Also scan NDK's unwanted symbols list (to show the things that we're
exporting but the NDK isn't. Symbols hidden in the NDK will be marked
with a *.

Add a -u (--unwanted) flag to disable the first two printed groups
(all symbols in bionic, all symbols in glibc). This is helpful when
wanting to grep in the list of unwanted symbols.

Finally, update the list of known differences between us and glibc.
