Hi, I'm trying to implement __builtin_setjmp / __builtin_longjmp for Sparc processors. I think I'm very close, but I can't work out how to issue BuildMI-type instructions to load the address of the recovery location (set in setjmp) into a register using the SETHI / OR combination. I can't see any equivalent code anywhere else in Sparc. I imagine this is similar if I try to make a CALLRi or CALLrr call, but looking through the code there isn't yielding any obvious solution to me. Would anyone be able to point me at a relevant piece of code that can...

Hello all, I am trying to modify the Sparc backend to do something for my team's project, to do the following. Whenever the backend encounters a call to one particular type of function names (functions like p0(), p1()..etc), I want the backend to generate a "sethi %g0, <number>", and NOT a "call p0, call p1..." instruction. However, the backend should work as usual for any other function name. Now I figured that there are two ways to do this : 1) Modifying the "SparcISelLowering.cpp" to emit a special SDNode (with a special o...

...assembly code because I need to encode the registers into the "number". For instance, if the call instruction is %result = call i32 @foo(i32 %a) and the result is assigned to register %l0 and the variable "a" to register %l1, then I encode all foo, %l0 and %l1 and generate a sethi instruction. thanks, Venkatraman On Thu, Jan 20, 2011 at 12:31 PM, John Criswell <criswell at illinois.edu> wrote: > On 1/20/11 12:27 PM, Venkatraman Govindaraju wrote: > > Just out of curiosity, have either of you considered writing an LLVM > transform that simply replaces th...

I'm looking over the RR list scheduler and am wondering about how the Sethi-Ullman numbers are used. The comments and the code indicate that the node with the lowest S-I number is scheduled first. Traditionally S-I scheduling schedules the node with the highest S-I number first. What am I missing? -Dave

Hello! Can someone please help me in building debug version of klibc ? I've cloned git://git.kernel.org/pub/scm/libs/klibc/klibc.git , but failed to build it with debug info added "-g" to HOSTCFLAGS in Makefile, but $ make -j KLIBCKERNELSRC=`pwd`/../linux-2.6/usr still strips every debug symbol , and i'm failed to change scripts/Kbuild.klibc and Makefile to remove strip

After the table is read, I get names of the variables (thro' the following code) as under quotes (like "V1" rather than the original representation V1)

Hi list, I added custom code to eliminate frame index references. I replace each FI reference with a subtraction from my frame pointer register (just like ebp in x86). Its result is stored in another register which is used by the load/store instructions. Nevertheless, this operation gives me redundant subs that I would like to remove after all fi references have been eliminated. For example:
