−State of blobs in FreeCalypso firmware
+
−======================================
+
−
+
−FC Tourmaline is almost completely deblobbed.  Only the following very small
+
−components exist in the form of blobs (prebuilt binary objects for which we
+
−have no exact corresponding source) in the standard Tourmaline build:
+
−
+
−* OSL and OSX glue components of GPF: 14992 bytes of code
+
−* TMS470 compiler's RTS library (libc/libgcc equivalent): 13152 bytes of code
+
−
+
−For OSL and OSX we do have reconstructed C code written based on disassembly of
+
−the blobs, but I (Mother Mychaela) do not consider the current state of this C
+
−reconstruction to be fit for production use - hence standard Tourmaline fw
+
−builds use blob versions of these components.  However, our configuration and
+
−build system gives you the freedom to select which version of each component
+
−you would rather use; the selection is made with Bourne shell config variables
+
−on the configure.sh invokation line:
+
−
+
−OSL=0	use the blob version of OSL
+
−OSL=1	use the reconstructed C version of OSL
+
−OSX=0	use the blob version of OSX
+
−OSX=1	use the reconstructed C version of OSX
+
−
+
−The current default is OSL=0 and OSX=0.

−RTS library
+
−===========
+
−
+
−We do have source code for some versions of the TMS470 compiler's RTS library,
+
−but they may not be exactly corresponding to the blob version from TCS211 which
+
−we are using.  This area is deemed to be such a low priority that no real
+
−investigation has been done yet.
