Any specific suggestions? The PTX code emitted from GCC differs only in
prologue/epilogue, so whatever's broken..
I'm proposing the following patch as a step towards resolving the issue with
inaccessibility of stack storage (.local memory) in PTX to other threads than
the one using that stack. The idea is to have preallocated stacks, and have
__nvptx_stacks[] array in shared memory hold current stack pointer
Hello,
I'm proposing the following patch as a step towards resolving the issue with
inaccessibility of stack storage (.local memory) in PTX to other threads than
the one using that stack. The idea is to have preallocated stacks, and have
