/* Short overview:
There are at the moment three different function entry formats preset.
The first is the MIPS one. The second version
is for ARM, PPC, SH3, and SH4 mainly for Windows CE.
The third is the IA64 and x64 version. Note, the IA64 isn't implemented yet,
but to find information about it, please see specification about IA64 on
http://download.intel.com/design/Itanium/Downloads/245358.pdf file.
The first version has just entries in the pdata section: BeginAddress,
EndAddress, ExceptionHandler, HandlerData, and PrologueEndAddress. Each
value is a pointer to the corresponding data and has size of 4 bytes.
The second variant has the following entries in the pdata section.
BeginAddress, PrologueLength (8 bits), EndAddress (22 bits),
Use-32-bit-instruction (1 bit), and Exception-Handler-Exists (1 bit).
If the FunctionLength is zero, or the Exception-Handler-Exists bit
is true, a PDATA_EH block is placed directly before function entry.
The third version has a function entry block of BeginAddress (RVA),
EndAddress (RVA), and UnwindData (RVA). The description of the
