kandi X-RAY | n64 Summary

n64 is a C++ library typically used in Utilities, Emulator applications. n64 has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Experimental low-level N64 emulator written in C and a bit of C++. Still under heavy development and not ready for prime time. Compatibility is not high and performance is not great (yet.). The goals of this project are to create a low-level emulator with good compatibility, while learning a lot along the way.

            QUESTION

            Does the prologue of a function can write outside of its frame?
            Asked 2021-Apr-03 at 23:28

            I'm currently trying to analyse the assembly of an old video game from N64. In order to do so, I'm using some N64 debugger to read and understand the underlying MIPS code.

            In one of the calls I'm looking at, the prologue is defined as follows:

            ...

            ANSWER

            Answered 2021-Apr-03 at 23:22

            One MIPS calling convention has the caller allocate stack memory space for all the parameters despite that the first 4 parameters (at least) are actually passed in registers.

            This means that the called function can store $a0, $a1, $a2, $a3 to the stack, expecting that those memory locations are available.

            When a function calls another function, then as a caller it should also allocate those same 4 words of stack space.  A function that calls another will need at least a minimal stack frame anyway, so having it allocate those 4 extra words is free in terms of prologue and epilogue.

            Part of older calling conventions would tend to include support for varargs (variadic functions) that may not even be properly declared in C code as such.  Allowing functions to store their parameters back to caller-allocated memory allows all the arguments to be flushed to memory and be contiguous, which is important for varargs functions.  And doing it for all functions is overkill but simplifies some issues.

            See https://courses.cs.washington.edu/courses/cse410/09sp/examples/MIPSCallingConventionsSummary.pdf for a picture of the stack frame that includes the 4 words for the register arguments.

            In practice I believe that the reservation of 4 words for the callee to use in the caller's stack space is highly overrated, and as evidence would note that this has been dropped in RISC V, for example.

            Some Intel systems use a red zone instead, which says that the system agrees not use your stack space within a certain small distance below the stack pointer (i.e. in the unallocated space of the stack).  This makes sense on intel as the return address is automatically written to memory so doesn't need to be separately pushed like on MIPS, yet these systems also benefit from some pre-allocated stack space for simple functions to use without necessarily setting up a stack frame (i.e. the red zone).

            I think a histplot would be a better way to visualize this problem if "ultimately, what i want to show is how the total sales of each title differs across platforms" This shows the frequency of games with standard deviations (grouped by game) in 0.1 bins. You can pass ddof=0 to not return NaN values, but that will change the standard devation of all values.

            Asked 2021-Jan-14 at 02:33

            I have a dataframe that consists of of video game titles on various platforms. it contains, among other values the name, critic's average score and user's average score. Many of them are missing scores for the user, critic and/or ESRB rating.

            What i'd like to do is replace the missing rating, critic and user scores with those for the same game on a different platform (assuming they exist) i'm not quite sure how to approach this.(note - i don't want to drop the duplicate names, because they aren't truly duplicate rows)

            What nvidia-smi shows is not the CUDA version that you have installed, but the maximum CUDA version that your driver supports.

            CUDA 11.0 has been announced but not released yet (as of June 2nd 2020), so you should use CUDA 10.2 as it's the latest available version.

            Subtotals per category not showing data (all subtotal columns show NULL)
            Asked 2020-Oct-20 at 18:14

            In my query I have one last obstacle I'm trying to overcome. My goal is to group products ("prod") by the specified category ("prodcat") and have a subtotal for each column's worth of data (such as JAN, FEB etc) at the end of each category.

            Below I included a link to picture of the data. It shows each column/category associated (B/O, On Hand, Commit, [Tot Avail], Jan, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV AND DEC) and a new row called 'subtotal - prodcat'. As I said, The data associated with each prodcat needs to be subtotaled at the end of each category. As you will see in the picture, while I have the 'Subtotal - [prodcat]' showing up at the end of each prodcat as intended, each column's worth of data has NULL for that row. I removed the prod names and prodcat names but you should still clearly see the issue I'm facing.

            Here is a link to an example output of what is currently happening

            I can't seem to figure out what I'm doing wrong. I have tried using CASE WHEN, GROUPING SET, ROLLUP etc and has worked. For some reason, nothing I have tried thus far allows the [subtotals - prodcat] rows (and subtotal - Overall as well) to have actual values and not just NULL.

            Below I went ahead and used SQL Fiddle to 're-create' what I'm trying to do. The code is the same outside of fictitious data. I've never used SQL Fiddle before so hopefully my write up is correct. The one thing I will say is that SQL Fiddle doesn't let you 'create views. However I use a 'view' in my process so I included the code for testing purposes below and to show EXACTLY the method I am using to get my results.

            64 bit immediates in llvm target code generation
            Asked 2020-Aug-04 at 09:18

            I am working on a research project where I am usingllvm to generate some assembly for a custom isa. I am feeding my assembly into a simulator for the time being. Part of my isa allows for 64 bit immediate values in an instruction encoding, I am using a modified version of the sparcv9 target with datalayout: E-m:e-i64:64-n64:64-S128. For some reason when I try to make an instruction for this, I am only getting the lower 32 bits of the value. When I expect to get "enter rd, 4629559679448514560" I instead get "enter, rd, 0" because the lower 32 bits are all 0 in this long.

            ANSWER

            Answered 2020-Aug-04 at 09:18

            Probably the problem is elsewhere and you'd need to check how the immediate is printed down to assembly file? Steps to check:

            1. Check how the SDAG is create
            2. Check how instruction is selected and what is an imm in MI
            3. Check MI=>MC lowering
            4. Check assembly printing.

            PS: You don't need PatLeaf here. Using just imm:$imm should work, there is nothing to check.
