# Patch to disable the use of -g in pcc-libs/csu/linux/ which is partly assembler code.
# Also, inlineing is disabled because it will break the code.
# Also, remove default -O flag from the code.

%description
The compiler is based on the original Portable C Compiler by Stephen
C. Johnson, written in the late 70's. Even though much of the
compiler has been rewritten, some of the basics still remain.

PCC debuted in Unix Version 7 and replaced the DMR compiler (Dennis
Ritchie's original C compiler) in both System V and the BSD 4.x
releases. Some history about pcc is in the A History of UNIX before
Berkeley: UNIX Evolution: 1975-1984 and in the Evolution of C.

About 50% of the front-end code and 80% of the back-end code has been
rewritten.  Most stuff is written by Anders Magnusson, with the
exception of the data-flow analysis part and the SSA conversion code
which is written by Peter A. Jonsson, and the Mips port that were
written as part of a project by undergraduate students at LuleĆ„
University of Technology (LTU).
