idea is to not emit struct debugging information in the current

another compilation unit.
Debug information for a struct defined in the current source
file should be generated in the object file. Likewise the
debug information for a struct defined in a header should be
generated in the object file of the corresponding source file.
Both of these case are handled when the base name of the file of
the struct definition matches the base name of the source file
of the current compilation unit. This matching emits minimal
struct debugging information.
The base file name matching rule above will fail to emit debug
information for structs defined in system headers. So a second
category of files includes system headers in addition to files
with matching bases.
The remaining types of files are library headers and application

/* Windows32 threads specific definitions. The windows32 threading model
does not map well into pthread-inspired gcc's threading model, and so
there are caveats one needs to be aware of.
1. The destructor supplied to __gthread_key_create is ignored for
generic x86-win32 ports. This will certainly cause memory leaks
due to unreclaimed eh contexts (sizeof (eh_context) is at least
24 bytes for x86 currently).
This memory leak may be significant for long-running applications
that make heavy use of C++ EH.
However, Mingw runtime (version 0.3 or newer) provides a mechanism
to emulate pthreads key dtors; the runtime provides a special DLL,
linked in if -mthreads option is specified, that runs the dtors in
the reverse order of registration when each thread exits. If
-mthreads option is not given, a stub is linked in instead of the
DLL, which results in memory leak. Other x86-win32 ports can use
the same technique of course to avoid the leak.
2. The error codes returned are non-POSIX like, and cast into ints.
This may cause incorrect error return due to truncation values on
hw where sizeof (DWORD) > sizeof (int).
3. We are currently using a special mutex instead of the Critical
Sections, since Win9x does not support TryEnterCriticalSection
(while NT does).
The basic framework should work well enough. In the long term, GCC
needs to use Structured Exception Handling on Windows32. */

# Support for allocating more stack space when using -fsplit-stack.
# When a function discovers that it needs more stack space, it will
# call __morestack with the size of the stack frame and the size of
# the parameters to copy from the old stack frame to the new one.
# The __morestack function preserves the parameter registers and
# calls __generic_morestack to actually allocate the stack space.
# When this is called stack space is very low, but we ensure that
# there is enough space to push the parameter registers and to call
# __generic_morestack.
# When calling __generic_morestack, FRAME_SIZE points to the size of
# the desired frame when the function is called, and the function
# sets it to the size of the allocated stack. OLD_STACK points to
# the parameters on the old stack and PARAM_SIZE is the number of
# bytes of parameters to copy to the new stack. These are the
# parameters of the function that called __morestack. The
# __generic_morestack function returns the new stack pointer,
# pointing to the address of the first copied parameter. The return
# value minus the returned *FRAME_SIZE will be the first address on
# the stack which we should not use.
# void *__generic_morestack (size_t *frame_size, void *old_stack,
# size_t param_size);
# The __morestack routine has to arrange for the caller to return to a
# stub on the new stack. The stub is responsible for restoring the
# old stack pointer and returning to the caller's caller. This calls
# __generic_releasestack to retrieve the old stack pointer and release
# the newly allocated stack.
# void *__generic_releasestack (size_t *available);
# We do a little dance so that the processor's call/return return
# address prediction works out. The compiler arranges for the caller
# to look like this:
# call __generic_morestack

/* This file implements the md_fallback_frame_state_for routine for
Windows, triggered when the GCC table based unwinding process hits a
frame for which no unwind info has been registered. This typically
occurs when raising an exception from a signal handler, because the
handler is actually called from the OS kernel.
The basic idea is to detect that we are indeed trying to unwind past a
signal handler and to fill out the GCC internal unwinding structures for
the OS kernel frame as if it had been directly called from the
interrupted context.
This is all assuming that the code to set the handler asked the kernel
to pass a pointer to such context information.
There is three main parts.
1) The first thing to do is to check if we are in a signal context. If
not we can just return as there is nothing to do. We are probably on
some foreign code for which no unwind frame can be found. If this is
a call from the Windows signal handler, then:
2) We must get the signal context information.
* With the standard exception filter:
This is on Windows pointed to by an EXCEPTION_POINTERS. We know that
the signal handle will call an UnhandledExceptionFilter with this
parameter. The spec for this routine is:
LONG WINAPI UnhandledExceptionFilter(struct _EXCEPTION_POINTERS*);
So the pointer to struct _EXCEPTION_POINTERS must be somewhere on the
stack.
This was found experimentally to always be at offset 0 of the context
frame in all cases handled by this implementation.
* With the SEH exception handler:
In this case the signal context is directly on the stack as the SEH
exception handler has the following prototype:
DWORD
SEH_error_handler (PEXCEPTION_RECORD ExceptionRecord,
PVOID EstablisherFrame,
PCONTEXT ContextRecord,
PVOID DispatcherContext)
This was found experimentally to always be at offset 56 of the
context frame in all cases handled by this implementation.
3) When we have the signal context we just have to save some registers
and set the return address based on the program counter (Eip).
