About 50% of the frontend code and 80% of the backend code has been rewritten. + +Build options (environment variables): +TLS - Enable thread local storage? Default=no, export TLS=yes to enable. +CC - Compiler to use. Default is to look for pcc, gcc, clang (in that order). + +This build is for the 1.1.0.BETA branch of pcc. The 1.0 branch no +longer works on modern Slackware versions (newer than 13.37). The old +pcc 1.0 had separate builds for pcc and pcc-libs; this build includes +the libraries so no separate pcc-libs is needed (or exists). + +Optional step: To bootstrap pcc, first remove any old versions of pcc +(and pcc-libs, if present), then build and install pcc twice (without +setting CC). The first time, pcc will be built with gcc. The second time, +it will be built with itself. + +Note: pcc is a C compiler only. There is experimental, incomplete support +for C++ and Fortran 77 in the pcc codebase, but neither is usable yet. |
