Suppress extern inline with HP-UX cc, as it appears to be broken; see
|
|
<https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
|
|
|
|
Suppress extern inline with Sun C in standards-conformance mode, as it
|
|
mishandles inline functions that call each other. E.g., for 'inline void f
|
|
(void) { } inline void g (void) { f (); }', c99 incorrectly complains
|
|
'reference to static identifier "f" in extern inline function'.
|
|
This bug was observed with Oracle Developer Studio 12.6
|
|
(Sun C 5.15 SunOS_sparc 2017/05/30).
|
|
|
|
Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
|
|
on configurations that mistakenly use 'static inline' to implement
|
|
functions or macros in standard C headers like <ctype.h>. For example,
|
|
if isdigit is mistakenly implemented via a static inline function,
|
|
a program containing an extern inline function that calls isdigit
|
|
may not work since the C standard prohibits extern inline functions
|
|
from calling static functions (ISO C 99 section 6.7.4.(3).
|
|
This bug is known to occur on:
|
|
|
|
OS X 10.8 and earlier; see:
|
|
https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
|
|
|
|
DragonFly; see
|
|
http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
|
|
|
|
FreeBSD; see:
|
|
https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
|
|
|
|
OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
|
|
for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
|
|
Assume DragonFly and FreeBSD will be similar.
|
|
|
|
GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
|
|
inline semantics, unless -fgnu89-inline is used. It defines a macro
|
|
__GNUC_STDC_INLINE__ to indicate this situation or a macro
|
|
__GNUC_GNU_INLINE__ to indicate the opposite situation.
|
|
GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
|
|
semantics but warns, unless -fgnu89-inline is used:
|
|
warning: C99 inline functions are not supported; using GNU89
|
|
warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
|
|
It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

section 2.4.3. Note that malloc(), sprintf(), and fwrite(), in

|
particular, are NOT async-signal-safe.
|
|
* All memory locations (variables and struct fields) that these functions
|
|
access must be marked 'volatile'. This holds for both read and write
|
|
accesses. Otherwise the compiler might optimize away stores to and
|
|
reads from such locations that occur in the program, depending on its
|
|
data flow analysis. For example, when the program contains a loop
|
|
that is intended to inspect a variable set from within a signal handler
|
|
while (!signal_occurred)
|
|
;
|
|
the compiler is allowed to transform this into an endless loop if the

|
variable 'signal_occurred' is not declared 'volatile'.
|
|
Additionally, recall that:
|
|
* A signal handler should not modify errno (except if it is a handler
|
|
for a fatal signal and ends by raising the same signal again, thus
|
|
provoking the termination of the process). If it invokes a function
|
|
that may clobber errno, it needs to save and restore the value of

errno. */

The naïve code (n1 > n2 ? 1 : n1 < n2 ? -1 : 0) produces a conditional

jump with nearly all GCC versions up to GCC 10.

GCC versions up to GCC 9.

The better code (n1 > n2) - (n1 < n2) from Hacker's Delight § 2-9

avoids conditional jumps in all GCC versions >= 3.4. */
