klcc - compile a program against klibc
klcc [gcc options] [-o outfile] infile...
klcc is a wrapper around gcc(1) and ld(1) which compiles and links a
program against the klibc tiny C library. It supports most gcc
Unlike gcc, klcc compiles with optimization on by default.
Furthermore, the optimization level used depends on whether or not -g
is specified, since klcc frequently uses options in the normal case
which makes debugging impossible. Therefore, compile without -g, -O,
-f or -m option to use the default optimization level; this will
generally result in the smallest binaries. You may want to use -s when
linking, however. Use -O0 to compile without any optimization
whatsoever; this may not work depending on the version of gcc used.
Use the -shared or -static option to compile for and link against
shared or static klibc. Note that shared klibc only supports running
against the exact same klibc binary as the binary was linked with.
In addition to standard gcc options, klcc supports options of the form
-print-klibc-option, which prints the corresponding klibc configuration
