% cd perf % make perf |
The output is `perf.tex', `perf.dvi' and `perf/index.html'.
Note that the measurement requires the following:
As an indication of the values you can expect here is part of the results for `make perf' on a 200Mhz Cyrix MMX (i386) chip which runs at about 200 BogoMips under FreeBSD 2.2.6 with `-O'.
`assert(i >= 2);' 28 bytes, 19ns.
`TRAD_assert(i >= 2);' 47 bytes, 20ns.(16)
`I(i >= 2);' 9 bytes, 18ns.
`DI(i >= 2);' 1 byte, 147.4us.
`I(A(int i=0, i!=10, i++, a[i]>=0));' 28 bytes, 287ns.
`d = now();' 8 bytes, 3.1us.
`printf("helloworld\n");' 13 bytes, 9.1us.
`L("helloworld\n");' 18 bytes, 8.9us.
`DL("helloworld\n");' 1 byte, 26.4us.
Note that these measurements were on a system that was configured with `I_DEFAULT=fast ./configure'. The default output of `./configure' produces nice error messages at the cost of increased code space.
