As Verilator continuously allocates and releases small objects (e.g.: AstNode, V3GraphVertex, V3GraphEdge), it spends a significant amount of time in malloc/free and friends. This patch adds the --enable-tcmalloc configure option to link Verilator against the high performance malloc implementation library libtcmalloc. The default is to use libtcmalloc if available on the system. Note that there are no source code change, we are simply replacing the standard library memory allocation functions. Measured major compilation speed improvement of 27% when running Verilator with -O3 on a large design. |
