RISC-V LLVM sync-up call 19 Mar 2020
...p in mind that the GP is only used to reach global variables of local scope and the GOT, where the address of global variables of global scope reside. This model assumes that the distance between the GP and the global data area, GOT and local scope variables is defined at link time. __ Evandro Menezes ◊ SiFive ◊ Austin, TX > On Mar 23, 2020, at 6:20, Sam Elliott <selliott at lowrisc.org> wrote: > > Eli, > > Yep, we’re looking at a ROPI/RWPI model for RISC-V and it is shaking out to be fairly similar to this model (though we’ve only been looking at it for 32-bit RISC-V). &...

RISC-V LLVM sync-up call 19 Mar 2020
...ng about devices without an MMU where the addresses are physically separated. Makes sense. This reminds me of rwpi on ARM; it has a sort of similar scheme of referring to data indirectly through a pointer, but it also changes the ABI to keep the pointer in a reserved register. -Eli From: Evandro Menezes <evandro.menezes at sifive.com> Sent: Friday, March 20, 2020 12:28 PM To: Eli Friedman <efriedma at quicinc.com> Cc: Alex Bradbury <asb at lowrisc.org>; llvm-dev <llvm-dev at lists.llvm.org> Subject: [EXT] Re: [llvm-dev] RISC-V LLVM sync-up call 19 Mar 2020 Hi, Eli.
