Ah, sorry.  There are so many posts sometimes, and it's easy to get 
mixed up.  Yes, for a new language you need at least part of a new 
compiler.

Even there, however, it can make sense to re-use existing systems.  llvm 
is designed specifically to be re-useable for different languages.  It 
won't fit all kinds of languages, of course, but if you can make an llvm 
frontend for your language then you get a great deal of features, 
optimisations, analysis, and code generation for free.  (gcc is also 
used like that, but my understanding is that it is easier with llvm.)

As you know, I don't place much value on the "small and fast" aspects. 
They can be convenient, but they are not something I see as important 
for picking a tool.

However, some of the other highlights are more interesting.  I would 
suggest that /any/ C compiler generates assembly that is "faithful to 
the original C" - anything else (baring bugs) would make the compiler 
useless.  But generating /clear/ assembly is something not all tools are 
good at.  Of course, there is often a conflict between generating 
assembly that is clear, and generating assembly that is efficient.

And obviously interaction with your own language is useful to you, and 
is not found in other C compilers.

I meant they don't exist from elsewhere - you have to write them 
yourself, rather than using ready-made tools.  I /know/ you have written 
tools for your own languages.  Whatever I may think of them or the 
wisdom of using private languages, I have never suggested they are 
vapourware.

There are /lots/ of things that can be done more easily in other 
languages than in C.  /Huge/ numbers of things.  And there are lots of 
things that can be done better in C than other languages.  This is the 
whole point - that is why we have lots of different programming 
languages.  Sometimes a task is best done in C, sometimes in Python, 
sometimes in Assembly, sometimes Lua, sometimes Haskell.  No one - not 
me, not anyone else in c.l.c as far as I am aware - has ever suggested 
that C is a perfect language, or the only useful language, or the "best" 
language.  All we ever claim is that it is a good and useful language, 
and can be used well by people who learn to understand it.

If this "typestr" feature is a useful feature of your language, then 
great.  I can see it being handy if your language is interactive, and if 
it has other generic features - perhaps for implementing a "println" 
function that can take many different types as arguments.  But call it a 
good feature of /your/ language - don't call it a missing feature of C. 
(C does not need such a feature in the same way - being statically 
typed, you can work out the type name of any expression.)

(In case you have forgotten, I have previously said that your 
"attribute" syntax here was nice.)

Yes.

Why would you guess that?  I wrote explicitly that fast is good, and 
small is good, all other things being equal.  If there was a tool that 
did everything that gcc does (at least the parts I use) and was smaller 
and faster, then it would clearly be better for me.  If it did 
/everything/ gcc does (including the stuff I don't use), and was an 
order of magnitude smaller and an order of magnitude faster, then I 
would certainly be impressed.

I don't remember writing something that would suggest such a thing.  I 
might have said something along the lines of it being hard to get new 
languages established, or that I would be wary of relying on new 
languages for serious use (though they can certainly be fun to try).

I have seen too many projects and professional developments that are 
orphaned because of using unusual languages (of which personal languages 
are just extreme cases).  I have seen lots of time and money wasted, and 
I have seen people desperately trying to keep ancient computers alive 
because they have such valuable code written in a language that only 
works on the old systems.

Sometimes a new language, or niche language, is the ideal choice for a 
task.  But there are many factors that influence the choice of a 
language, and the use of established and known languages is a major 
factor.  It is, in most cases, far better to use a mainstream language 
like C, Java, Python, PHP, etc., even if some alternative language could 
let you do the task in half the time with half the length of source 
code.  That is because most programming tasks don't end with the first 
delivery.  The customer usually wants to know that when they need a new 
version in a few years time, they can find qualified programmers, get 
new versions of the programming language, and make changes to the 
software without having to redo everything from scratch in a different 
language.

That does not mean I won't use new languages - I have done so, a number 
of times.  But it means I am wary of them, and will use a new language 
only with very good reason.

This can depend on many details.  I see whole-project all-at-once 
compilation used primarily on small systems where the scope is limited 
but the advantages great, such as on certain kinds of small 
microcontroller.  For bigger systems (more than, say, a dozen source 
files), it seems to work better to have each file "compiled" separately 
into an "object" file containing an analysed and optimised internal 
format.  A good deal of such work can be done locally, within functions 
or between functions within a file.  /Then/ the files can be combined 
for inter-module and cross-module optimisations, and then final code 
generation.

Fair enough.  At that time, many established tools /were/ more limited, 
and it was more common to use odder languages and tools.  Times have 
changed, however.

No, obviously not.  Why would I want to do that?

If you want to build a new house, and ask a builder company how long it 
will take, do you expect them to include the time taken to build the 
brick kiln and cement factory?

That sounds likely figures.

ccache is not a compiler.  It is a compiler cache.  It works by taking 
the pre-processed source, and hashing it along with the compiler 
version, flags, and options, and recording the generated output.  Thus 
when you do exactly the same compilation again, it will give you the 
cached output.  It is quite handy if you are dealing with repetitive 
builds, especially if there is not a good incremental build process.  I 
didn't need it for Lua, I just tested its timings here for fun.  (Fun is 
always a good motive.)

In the C world, these are rarely a problem.  Computer speeds have kept 
up with code sizes well enough for most purposes.

In the C++ world, on the other hand, these /are/ a problem - and compile 
speed is an issue there, as you might have a thousand lines of C++ that 
uses a million lines of headers.  The solution there is not faster 
compilers, but a better module system.  (And yes, this is a limitation 
that comes from C++'s background in C which does not have a good module 
system.  Any major newer language would provide some kind of module 
system from the start.  It's nice to see you have that too.)

Certainly.  And for any new language, it makes sense to have some kind 
of modules from the start.

But for C, a prime aspect of the language is that it does not change 
much.  And adding extra hardware has been solving the compile speed 
issue quite happily for a long time - C compilation speeds on reasonably 
priced workstations have been getting faster over the years, despite 
increases in the size of code bases.  So there is no need to add modules 
to C.

(C++ is a different matter.)
