Detailed Description

This class provides access to the stay-behind GLISS data structures and code provided by the GLISS v2 utility used by some loaders.

This allows to re-use GLISS to embed ISA-specific processing inside some analysis (typically pipeline analysis).

The existence of this object is tied to the gliss::INFO_FEATURE and linked to the process with the identifier gliss::Info::ID.

Member Function Documentation

bool otawa::gliss::Info::check ( t::uint32  checksum )

pure virtual

As the validity of the data used in Gliss is strongly coupled with the data of an analysis using this object, OTAWA provides a way to generate a checksum of the file isa/id.h and to compare both values stored in the loader and in the analysis with this function.

If the check fails, it is utterly risky to use this structure.

Parameters

Checksum

to check.

Returns

True, both checksum are compatible, false else.

void * otawa::gliss::Info::decode ( Inst *  inst )

pure virtual

Decode an instruction and return its descriptor.

The returned descriptor must be released with Info::free().

Parameters

inst	Instruction to decode.

Returns

Decoded instruction.

Referenced by decode().

template<class T >

void otawa::gliss::Info::decode< T > ( Inst *  inst, T *&  desc  )

inline

void Info::free(void *desc); Free a GLISS instruction descriptor previously allocated by Info::decode().

Parameters

desc	Instruction descriptor to release.

A type-wise way to perform the decoding of an instruction. The returned descriptor must be fried with Info::free().

References decode().
