[ECOS] A basic question regarding [eCos] performance figures

[sandeep <shimple0 at yahoo dot com>]

when one cites various eCos performance figures
related to footprint and timings for core functions
(as printed via tm_basic tests) --

are those generated using certain compiler flags (like
-O2, -Os etc.) applied during compilation and some
linker flags for relaxation pass etc. during linking -
to reduce code size and also have impact on execution
timings.

also i would like to seek opinions of experts on - 
is there any issue with the process of code-tweaking
that is tied down to how the toolchain in question
generates code with particular compiler flags, though
this way it generates tighter object code, that would
improve code size and speed? this kind of things can't
be done for common code though.

sure, this might at times, render the source code, not
easily comprehensible. but should this matter to me as
a user, if i am not given the source code, just the
binaries and needed headers.

regards
sandeep
