configure bug? / questions to gcc
Wed Apr 8 01:12:00 GMT 1998
I have some questions:
1. Why does egcs-980404 install libf2c into /usr/local/lib
when doing a 'make cross;make install'?
There it overwrites the native version of it, which makes
the native g77 worthless. I think it should go into
2. I usually make an obj directory an then a
I realized, that configure changes <source-dir-of-egcs>/
(I think i configured first cross compiler for a
different target system, made it and after a
rm -rf obj/* i configured for the native compiler.
Then the compilation failed) After i reinstalled the
source, it went o.k. I thought, that the trick with the
obj-dir is, that you can have your sources mounted read-only.
Isn't this correct?
3. I would like to do some hacking of gcc/g77. Is there some
documentation about the compiler internals? How does it work?
Which intermediate code? How is code-generaion done? What
has the front end to provide, which file implements what?...
How long did it take you to get an principal idea of the way it
Best regards and thanks for help,
