Assumed key role in designing and developing the C++ front-end for zvm: 1. Code coverage / branch-coverage instrumentation involved recognition of statements at basic block level, generation of an empty-else statement, generation of file level constructors for data structure registration and optimization of the data structure to a three dimensional array. 2. C++ instrumentation for data race and memory error detection involved generation of inlined instrumentation for complex expressions, ensuring semanti

Designed and developed many Fortran 2003 enhancement. Designed and developed IEEE floating point features in Fortran compiler. It requires changes in grammar, lexical analyzer, syntax analyzer and semantic analyzer. Designed and developed a IR optimizer for Fortran compiler it gives ~16% runtime performance in one of the Fortran bench mark. Implemented pre-compiled header file optimization in Fortran compiler which reduces compile time as well as memory usage. Developed a small utility by using Perl and

Hybrid Programming Language Compiler for C/C++ and Fortran

Compiler optimization for precompiled header files to reduce compile time and memory usage

Research Disclosure publication service

This disclosure propose a Compiler Front End optimization on Precompiled Header File (PCH).

Method to inline Intrinsic functions in languages supporting array assignment.

Research Disclosure publication service

The Objective of the present disclosure is to provide an inline expansion method that can be universally applied to a variety of intrinsic function calls having at least one argument as array valued expression or array variable. In the present idea, intermediate representation containing intrinsic function call is analysed and optimized intermediate representation on inline expansion is generated in the loop where the argument is evaluated from the array valued expression or variable.
