[LLVMdev] llvm-gcc-4-2 development branch is open

[Devang Patel]

Hi All,

llvm-gcc-4-2 development branch is now open for development at

	llvm.org/svn/llvm-project/llvm-gcc-4-2

It is not yet ready, it can not even bootstrap. I welcome LLVM  
developers to test and apply fixes!

However, first take a note of ground rules :

1) LLVM developers, use your write access as judiciously as you use it  
for LLVM development and follow same check-in procedure.

2) I'd appreciate if LLVM specific code is covered by appropriate  
markers. There are tons of existing examples in current sources.  
Entire LLVM support patch is covered by these markers. I might have  
removed code from llvm-gcc-4.0 that was required for LLVM support but  
was not covered under /* APPLE LOCAL <begin|end> LLVM */ markers. If  
someone feels strongly about word APPLE  in these markers then feel  
free to change **ALL LLVM specific** markers to say /* LLVM LOCAL  
<begin|end> */.  However, please do not change other markers that  
carry "APPLE LOCAL" string.

3) This svn module is for GCC-4.2 based front end for LLVM. Please do  
not check-in code from FSF GCC mainline (which uses 4.3 as version  
number). If you need a LLVM front end based on GCC 4.3, please create  
separate llvm.org/svn/llvm-project/llvm-gcc-4-3 module.

4) Keep llvm-gcc-4-2 GPLv3 free. Which means, do not back port code  
from other GCC development branches that has adopted GPLv3 lic. If   
FSF GCC 4.2 branch adopts GPLv3 then consult llvm oversight group  
first before back porting code from FSF GCC 4.2 branch.

Thing that require immediate attention :

1) /* FIXME FIXME */ markers. :)

2) In GCC-4.2 CONSTRUCTOR_ELTS are now represented as VEC instead of a  
tree node chain.

3) FILE_TYPE, CHAR_TYPE etc.. tree nodes are gone.

4) In llvm-gcc x86 world, SSE intrinsics are listed in header file,  
where as FSF GCC lists them in source file. When I removed list  
from .c file, I did not synchronize it with .h file content.  I'll let  
x86 code gen folks worry about it :)

5) There are many GCC tree structure changes that I have not noticed  
yet.

Note, llvm-gcc-4-2 does not replace llvm-gcc-4-0. Current llvm-gcc FE  
(which is based on GCC-4.0) will be added in llvm svn at llvm.org/svn/ 
llvm-project/llvm-gcc-4-0. I have not picked up llvm-gcc-4-0 check-ins  
done in last few days in initial llvm-gcc-4-2 checkin.

Enjoy!
