Translation environment and translator

[Bob Nelson]

My interest in this new topic was piqued by santosh's recent posting
concerning the subject of ``diagnostic message'' here in clc.

After reading the C99 standard (``n1256.pdf'') , I am unclear if the
requirements of the ``translator'' are fulfilled if a translator does
nothing more than emit appropriate diagnostics -- without taking any
additional steps that could possibly lead to an executable program.

In short, does a tool such a <platform_speci fic>``lint''
</platform_specif icmeet the definition of a translator according the
language definition?

See 5.1.1.2(8) of that document, and also 5.1.2.3, especially section (5).

No, it doesn't. Otherwise, so would the following DOS batch file:

@echo off
rem I'm a C compiler! No, really I am!
echo Your program (if you even have one)
echo may contain a syntax error or a
echo constraint violation. Or, on the
echo other hand, it may not. But I
echo decided in any case not to bother
echo to compile your code. HAND.
exit

Thanks for making this crystal clear Richard. I was guilty of taking phrases
in the standard such as ``as is'', ``abstract machine'' and forms of
implementation-defined behavior to completely illogical extremes.

How much is a support contract for your ``compiler''? :-)

Sounds like you've got a great career ahead of you in clc.

Excellent. Well done.

And, like most CLC regs, it sounds like any real career he might have
had is kaput, so he should fit right in around here.

*SPLURF* And it happens once again: There are dozens of coffee stains
all over my TFT. I really should not drink coffee while reading clc.

Your compiler is hilarious! ;-)
