RISC-V LLVM sync-up call 19 Mar 2020
If I’m following correctly, there are two size-limited areas. One area, limited to 2GB, is the “text” area. This contains all the code. Then there’s a “global” area, limited to 4GB, which is pointed to by the global pointer. This contains the GOT, plus a flexible area that the object file can stick small bits of data into. And then outside of both of those, additional data is unlimited.
It

RISC-V LLVM sync-up call 19 Mar 2020
Hi, Sam.
I think that it's a fair comparison.
Keep 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.

RISC-V LLVM sync-up call 19 Mar 2020
Oh, I wasn’t really thinking 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.

[RFC] Upstream development of support for yet-to-be-ratified RISC-V extensions
# Overview and background
RISC-V is a free and open instruction set architecture. It is a modular
specification, with a range of standard extensions (e.g. floating point,
atomics, etc). New standard extensions are developed through RISC-V
Foundation working groups. The specifications for such extensions (e.g. vector
and bit manipulation) are publicly available, but are still in flux and won't

Incorrect degrees of freedom for splines using GAMM4?
Hello,
I'm running mixed models in GAMM4 with 2 (non-nested) random intercepts and
I want to include a spline term for one of my exposure variables. However,
when I include a spline term, I always get reported degrees of freedom of
less than 1, even when I know that my spline is using more than 1 degree of
freedom. For example, here is the code for my model:

Building the CRT
Folks,
I'm at a loss trying to add Compiler-RT to an LLVM build, even after
checking out the instructions at http://compiler-rt.llvm.org, so I'd
appreciate your help.
I've tried adding the CMake options LLVM_ENABLE_PROJECTS,
LLVM_BUILD_EXTERNAL_COMPILER_RT, LLVM_EXTERNAL_COMPILER_RT_SOURCE_DIR,
CLANG_DEFAULT_RTLIB. All to no avail.
FWIW, I'm building for the targets

[LLVMdev] Querying instruction classes
I'd appreciate some help in figuring out how to determine which
InstrItinClass an instruction belongs to.
For example, an InstrItinClass is defined in Schedule.td as:
def FOO : InstrItinClass;
Which is then used to build an InstrItinData in ProcessorItineraries and
to specify the class of a particular instruction.
I'd like to find out from a given instruction which class it belongs

[riscv] How do I use the RISC-V Vector extension instructions in LLVM IR?
Hi Everyone,
I am wondering how to use RISC-V V (Vector) extension instructions in
LLVM IR. In 2019 Kruppe and Espasa gave a talk [1] overviewing the
Vector extension and on slide 16 [2] they show LLVM IR samples which use
the vector instructions through intrinsic functions, such as:
%vl = call i32 @llvm.riscv.vsetvl(i32 %n)
At the time of the talk (April 2019) LLVM support for the V

random sample set for regression
Hi,
I'm not a programmer, so I have a question about R functions,
I run the Random Forest regression models, but
I would like to run the random forest model 1000 times with different
random sample set. to check the uncertainty of the regression model
estimates.

Sebastian,
If not a test, how about a patch in the documentation for TableGen about
this new feature that you're making available?
