pcc (Portable C Compiler) is based on the original Portable C Compiler
|
|
by S. C. Johnson, written in the late 70's. 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 release of pcc. The 1.0 release 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.
