And the libc interface is the one that will remain stable. The OS
calls may actually change between semi-major versions. Like the 32-64
bit move, when new calls came to be added, but some old ones actually
had to change. 

Then the libc code had to be used to smooth over, so 32-bit calls still
took 32-bit arguments and used 64-bit OS calls.

This is one of the places where the OS-user mode interface looks almost
directly taken from Tops20. The BSDs are quite different.

The only thing below libc is syscalls, and those are subject to change
without notice; the same application running on different systems--or
even the same system after an upgrade--may require different syscalls,
and libc makes all that completely transparent.

Why would you want to involve yourself in that mess?  Just call libc.

I have yet to see code breakage from changed syscall ;)
If you do assembler , you don't wont 500kb of libc bloat ...

That's about what I was thinking.  Assembler or a compiler for some other
language.

Then either you're using the INT 80 interface, which is an order of
magnitude slower than SYSENTER/SYSCALL, or you've never tried porting
code that uses SYSENTER/SYSCALL (which aren't always present), and
you've never had to deal with EBP not being restored properly and
needing to retry when a syscall is interrupted.

__kernel_vsyscall() handles all of that for you, but if you're going
that far, you might as well use syscall(), and then you might as well
use the regular C wrappers that convert between normal and syscall
calling conventions--and save you having to look up syscall numbers.

Linking to libc adds ~1500 bytes (mostly fixed overhead) to my hello
world program.  Considering all of the power that libc offers, that
seems like a minuscule price to pay.

Hm. int 0x80 does not preserve ebp rather it uses it as sixth parameter.
It is not that much slower on newer cpus. 
In 64 bit code, syscall instruction is used rather then int 0x80.

If you do static linking you will see actual size.

What makes you think that the size reported when using dynamic
linking is not an actual size?

What answer do you expect?
Make program that uses input by linking with libc function eg scanf
and other by using syscall.
It is easy to see some 500kb added to program in memory, while with no 
glibc linked,program takes 4kb...

 Virtual Address Space occupied by process
 Resident Set Size (number of pages in memory)

In the case of a statically linked executable, all the dependent functions
are linked into the application, so it's text size (on disk) will be larger.
The RSS will depend on the application access pattern - any text pages never
referenced will never become part of the RSS (i.e. be paged into physical memory).

In the case of a dynamically linked executable, all the dependent functions are
provided by shared objects.   When an executable is loaded, all the shared objects
required are also loaded (in many cases, such as libc, they'll have been loaded
already on behalf of another process and the newly exec'd process will shared
the existing text pages (but get CoW data pages which will allocate as soon as
the new process writes to them)).

Regardless of whether the application is dynamically or statically linked,
the amount of writable memory (stack, bss, data) will be identical between
the two.

How come then simple assembler program linked with glibc has RSS of
734kb, but assembler program that is not has RSS of 4kb?

	Because that much of libc is resident - whether it is used by your
assembler program or not it is resident and so because the whole thing is
mapped into the virtual memory of the process and that much is resident
your process shows as having that much RSS - in truth the majority of it is
shared with other processes and will never be accessed by your program.

	Memory accounting with shared libraries is messy because of things
like this.

Sorry, I never took into this seriously. Quick google search showed me
that `pmap -XX pid` shows how much is shared. Seems that all of the 
glibc is shared as glibc RSS matches shared memory;)
Bah, everyday one learns something new ;)

Chances are, some other program is already running that uses libc.
If such is the case, it's already in memory.  Why not use it?

My system doesn't even _have_ a libc.a because static linking to libc is
not a remotely reasonable thing to do.

There is no syscall for scanf(), so that's apples and oranges.

My hello world asm examples are 344 bytes for an executable that uses
the write() and exit() syscalls directly and 1875 bytes for one that
uses the libc wrappers.  That's trivial once you realize that's mostly
fixed overhead, not per call or even per wrapper.

Of course libc.so gets mapped into the latter example's address space,
along with a couple other things, but so what? They're already in RAM
(and probably L2 cache, if not L1) due to use by other processes, so the
real-world cost of that is zero.

my hello that uses read/write exit syscalls is 266 bytes (64 bit).
somewhat complicated glibc example that uses scanf/fopen/fwrite/fclose
exit is 1293 bytes also 64 bit.

Nevermind, I didn't pay attention to shared memory. Those 500kb or so
are actually shared with other processes ;)

That's only relevant if your new program is the only one on the system

I don't think so... linking with glibc adds resident usage of 500kb to 
program memory.
