Less memory means: less cache misses. This reduces the execution time of gperf on large inputs by ca. 2.5%. * src/bool-array.h (Bool_Array): For the _storage_array and _iteration_number fields, use 'unsigned char' instead of 'unsigned int'. * src/bool-array.icc (Bool_Array::Bool_Array, Bool_Array::clear: Update. * src/bool-array.cc (Bool_Array::~Bool_Array): Update.
This is GNU gperf. It is a program that generates perfect hash
functions for sets of key words. A perfect hash function is:
A hash function and a data structure that allows
recognition of a key word in a set of words using
exactly 1 probe into the data structure.
The doc/gperf.html file explains how the program works, the form of
the input, what options are available, and hints on choosing the best
options for particular key words set.
See the file NEWS for a list of major changes in the current release.
See the file INSTALL for compilation and installation instructions.
See the file JOIN-GNU to read how you can join the GNU project.
Output from the GPERF program is used to recognize reserved words in
the GNU C, GNU C++, and GNU Pascal compilers, as well as with the GNU
indent program.
