should happen wherever the header file is #include'd rather than
in the header file itself.

PR 17502: this header file still #include's internal stdio-related
header files and references the FILE structure, even if stdio is
disabled. There were some #ifdef's for CYGPKG_LIBC_STDIO already.

CYGPKG_LIBC_STARTUP component. Also add options for main()'s
arguments (CYGPKG_LIBC_ARGUMENTS), main()'s default stack size
(CYGNUM_LIBC_MAIN_STACK_SIZE), number of atexit handlers
(CYGNUM_LIBC_ATEXIT_HANDLERS), and whether _exit() stops the

atexit handlers and fflushs all the stdio streams. Add plenty of
tracing of asserts too.

It's been a long week.
 
Fri Aug 28 18:59:20 1998 Hugo Tyson <hmt@cygnus.co.uk>
 
* src/support/cstartup.cxx: Add a weakly named main to allow the
default configuration to link on the tx39 which has no
scalextric linking yet. The static Cyg_Thread main_thread object
below continues to exist, though unreferenced, so all its
descendants must exist too.

src/stdio/common/stdioinlines.cxx:
Changed to take account of the above

sprintf and sscanf tests are included again.

This causes hardware exceptions like

handle these exceptions in a generic way using
the appropriate signal handlers. The details of
exactly which exceptions are passed through
under what circumstances depend on the

be guaranteed to be invoked in the expected

that the architecture is unable to detect that
exception."

/v2_0/ChangeLog
0,0 → 1,101
2003-02-24 Jonathan Larmour <jifl@eCosCentric.com>
 
* cdl/signals.cdl: Fix doc link.
 
2003-02-13 Jonathan Larmour <jifl@eCosCentric.com>
 
* include/signal.inl (raise): Use if/else rather than switch to
avoid GCC 3.2 bug.
 
2002-05-23 Jesper Skov <jskov@redhat.com>
 
* cdl/signals.cdl: Don't build signal2 test when it'll N/A
anyway.
 
2002-04-30 Jesper Skov <jskov@redhat.com>
 
* cdl/signals.cdl: Added
CYGPKG_LIBC_SIGNALS_TESTS_SIGNAL2_TEST3_SKIP.
Removed again.
 
* tests/signal2.c: Instead check for
CYGNUM_HAL_EXCEPTION_FPU_DIV_BY_ZERO to decide if test3 is
appropriate.
 
2001-05-02 Nick Garnett <nickg@cygnus.co.uk>
 
[x86 branch]
* tests/signal2.c (cause_memerror): Added code for I386
architecture to provoke General Protection Fault.
 
2001-04-27 Bart Veer <bartv@redhat.com>
 
* tests/signal2.c (main):
The FPE test is applicable to the updated synthetic target.
 
2001-04-17 Bart Veer <bartv@redhat.com>
 
* cdl/signals.cdl:
Synthetic target now supports exceptions
 
2000-09-14 Jesper Skov <jskov@redhat.com>
 
* tests/signal/signal2.c: Prevent that GCC optimizes away the
cause_fpe call.
 
2000-09-07 Jesper Skov <jskov@redhat.com>
 
* tests/signal2.c: Fix compiler warning. Also reset FPU exception
vectors. Check for SH7708, not EDK7708 in test3 skip code.
* tests/signal1.c: Fix compiler warning.
 
2000-05-16 Jesper Skov <jskov@redhat.com>
 
* tests/signal2.c: Also reset DIV_BY_ZERO vector.
 
2000-05-08 Jesper Skov <jskov@redhat.com>
 
* tests/signal2.c: Skip test3 on SH7709A.
 
2000-05-02 Jonathan Larmour <jlarmour@redhat.co.uk>
 
* New package
Separated original libc out into separate packages on functional
boundaries.
Header files are now managed by isoinfra package
Plenty of cleanups done, but no major functionality changes
