| Abstract | Existing research understates the benefits that can be obtained from inlining and cloning, especially when guided by profile information. Our implementation of inlining and cloning yields excellent results on average and very rarely lowers performance. We believe our good results can be explained by a number of factors: inlining at the intermediate-code level removes most technical restrictions on what can be inlined; the ability to inline across files and incorporate profile information enables us to choose better inline candidates; a high-quality back end can exploit the scheduling and register allocation opportunities presented by larger subroutines; an aggressive processor architecture benefits from more predictable branch behavior; and a large instruction cache mitigates the impact of code expansion. We describe the often dramatic impact of our inlining and cloning on performance: for example, the implementations of our inlining and cloning algorithms in the HP-UX 10.20 compilers boost SPECint95 performance on a PA8000-based workstation by a factor of 1.32. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
