LLVM Backend : Replacing indirect jmps for x86 backend

由 北慕城南 提交于 2019-12-07 17:53:47
问题 I want to replace indirect jmp *(eax) instructions in the code to mov *(eax),ebx; jmp *ebx for the x86 executables. Before implementing this, i would like to make LLVM compiler, log an output every time it detects a jmp *(eax) instruction by adding some print statements. Then i want to move on to replacing the indirect sequence. From what i have seen from google searches and articles, i can probably achieve this by modifying the x86asmprinter in the llvm backend. But i am not sure how to go

Why are the “Paste JSON As Classes” and “Paste XML As Classes” commands disabled (grayed out) in Visual Studio? [closed]

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I'm using Visual Studio 2017 15.9.0 Preview 4.0 . I'm trying to use the " Paste XML As Classes " command available under "Edit > Paste Special" but it's grayed out: I got the (incorrect) feeling that this command would allow me to pick a file that contained XML, or have some other sort of UI. The articles I None of the articles I found talk about cases where these commands are disabled, and all indications lead me

How to generate Fortran subroutine with SymPy codegen

由 血红的双手。 提交于 2019-12-06 08:35:16
问题 I want to generate a Fortran subroutine with SymPy codegen utility. I can generate a Fortran function without problem with codegen(("f", x*y*z), "f95", "filename") . But I want to generate a Fortran subroutine so I can modify input arrays. How can I do this? The documentation is very poor. 回答1: The codegen utility creates a function if there is a single scalar return value, and a subroutine otherwise. There is some support for arrays, but the array functionality won't be triggered unless you

Xcode 9 build issue with Date vs NSDate for NSManagedObject

由 时光毁灭记忆、已成空白 提交于 2019-12-06 00:05:57
问题 Xcode 9 generates different code for Date type attribute of the entity in simulator vs device. I have codegen feature under Class set to category/extension in coredata. Until Xcode 8.3 (latest) it was all working fine ( NSDate always). Below is the auto generated code by Xcode 9 (Swift 4) for the attribute - On Device :- @NSManaged public var requiredDate: Date? AND, On Simulator :- @NSManaged public var requiredDate: NSDate? Anyone encountered this problem? What is the best solution for a

How to use C library created by MATLAB Coder codegen in C program with emxArray arguments?

由 北慕城南 提交于 2019-11-26 11:39:32
问题 The C function (C static library) created by codegen takes an input argument of type const emxArray_uint32_T and return values of type emxArray_struct_T . As the type suggests, input is an array of uint32 and output is an array of struct. I\'m not sure how to use this function in my C program. For the input, should I declare an array of type uint32_T or use the type emxArray_uint32_T ? For the output, because I don\'t know the size of the output array, how to declare the array of struct to
