Dears All ,
I am not a C/C++ programmer and my knowledge about them is very weak .
In my life I did never write a "Makefile" and my knowledge about it is
completely zero.
I want to learn Clang and LLVM as much as possible , mostly because I want
to write a Pascal front end for LLVM by using Clang compiler parts as much
as possible .
For this reason and on message by Tom Stellard
http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-November/078682.html
[LLVMdev] 3.5.1 Release Schedule
"Below is the proposed release schedule for LLVM 3.5.1. As always,
we need testers, so if you are interested in helping with that, let
me know."
I wanted to download Release 3.5.0 and apply tests on it .
If I can do this I could also apply my experience to release candidates .
With respect to my experiences , a
developer uses an accustomed line of testing and may not cover all of the
possibilities
which doing such a coverage is an impossible task . Another person not
knowing the system very well may follow a different line and may discover
some problems on this different line .
Therefore being ignorant about LLVM system is not so much detrimental for
testing .
I had installed in Linux ( Fedora 20 x86_64 ) OS supplied Clang 3.4.10 and
LLVM 3.4.10 .
Sometimes I am using Clang to compile small programs alongside with GCC
4.8.3 .
This is especially useful because sometimes one is detecting an error but
another one is not .
Therefore during program development , using different compilers on the
same program
is an excellent "code review" by a compiler as a "very high quality expert"
.
I am sorry about being verbose but I wanted to be explicit as much as
possible .
I have downloaded

into a directory ...../www.llvm.org/3.5.0/ ( where ..... is the upper
directories list ) .
I have decompressed them by using the Ark of KDE into the above directory .
The created directories are as follows :

...../www.llvm.org/3.5.0/clang-tools-extra-3.5.0.src/

By thinking the root of the above components would be LLVM ,
I have opened a Console terminal into
...../www.llvm.org/3.5.0/llvm-3.5.0.src/
Since there were existing
"configure"
script and a "Makefile" , I have applied it with following make execution .
The make completed without an error .
The make only processed the ...../www.llvm.org/3.5.0/llvm-3.5.0.src
directories .

--------------------------------------------------------------------------------
Opinions :
Within page
http://llvm.org/releases/download.html#3.5.0
inclusion of a file with a name such as
"LLVM_and_Clang_Building_from_Sources_of_3_.5.0.txt"
containing information about building the components from downloaded source
files would be very useful where "3.5.0" part will always be related to
supplied version .
Inclusion of two parts may be useful :
Building with an existing installed CLang / LLVM system
Building with generated CLang / LLVM system from downloaded source files
If it is may be useful , a part for
Building with an existing installed GCC system
may be included .
If such a file is supplied , I can apply and report my experiences with the
expectation that my opinions will not be ragarded as critisms but only
telling the difficulty points where "Thank you" part perhaps may be
forgotten .
I will use Linux x86_64 .
If you need another free x86_64 class OS , I may try or inform you about my
difficulty about it .
-----------
Build related and ReadMe.txt files are not consistently designed and
included .
-----------
Inclusion of a Documentation related file containing all of the
documentation related files
in the following list would be very helpful :
http://llvm.org/releases/download.html
The current state is the following :
In page
http://llvm.org/docs/
there is the following sentence :
If you are using a released version of LLVM, see the download page to find
your documentation.
Clicking on the "the download page" is leading the page
http://llvm.org/releases/
On this page , clicking "docs" is leading to the page :
http://llvm.org/releases/3.5.0/docs/index.html
In that page , there is the following sentence :
If you are using a released version of LLVM, see the download page to find
your documentation.
Clicking on the "the download page" is leading the page
http://llvm.org/releases/
i.e. , there is a circular referencing between links .
The expectation is a complete tarball to download .
-----------
There is no any consistent system of
configure
make
structure within downladed source files .
I am working on many other sources which almost all of them are
working either with this pair or with make .
Even if CMake is used , the make is using that system .
-----------
Thank you very much .
