XC32汇编程序错误

我在CRT0.S＆Lt:Edg＆Gt中看到了这个代码，添加了代码的其余部分。

JimIt不是真正的程序。它是极端剥离的版本来演示问题。CRT0不被使用。我只将一个文件组装到一个对象。没有链接，没有创建程序！请参阅POST后面的命令行，没有提到的标志创建对象是OK的，没有错误，没有警告XC32 GCCS与MIPS，GCC创建的对象是可以的，即使有上面的标志。艾伯特。



      以下为原文

    @Jim
It is not real program.
It is extremaly stripped down version to demonstrate problem.
 
crt0 is not used.
I only assembly one file to one  object. No link, no create program!
 
See command line in post #1
 
Without  mentioned flags created object is OK and there is no errors and no warnings with xc32-gcc
With mips-gcc created object is OK even with flags above.

你报告过这个bug吗？



      以下为原文

    Have you reported this bug as suggested ?

嗯，不，我不打算。程序的改进应该是它的创建者的首要任务。我的首要任务是为遇到同样问题的用户节省时间。艾伯特



      以下为原文

    Hmm, no. And I'm not going to.

Improvement of the program should be a priority for its creators.
My priority is to save time for users who come across the same problem.

Albert

该计划的改进显然是其创建者的优先事项。这就是为什么他们要求用户报告错误，Jackass。如果你不愿意向他们报告，不要麻烦把它带来这里-你没有帮助任何人。



      以下为原文

   
Improvement of the program is obviously a priority of its creators.  That's why they ask users to report bugs, Jackass.
If you're not willing to report it to them don't bother bringing it here - you're helping no one.

如果我在论坛上发现类似的问题，它会对我有帮助。我很遗憾你没有那么幸运。艾伯特



      以下为原文

    If I find a problem similar to mine in the forum, it will help me.
I regret that you are not so lucky.

我认为这是一个编码问题。SpNET是“伪代码”，而不是一个完整的测试例子（如POST 3中的OP所说）。CRT0.S工作很好，我经常使用它，在生产构建中有符号和列表文件。



      以下为原文

    I think this is a coding problem.
The spinet is "pseudo code", not a complete example to be tested ( as stated by the OP in post 3).
crt0.S works fine, I use it regularly, with symbols in the production build and a list file.

这就是我们不同的。你看，我检查过。两个不同的节目。模拟器上和硅上都有这种“伪代码”在上面提到的配置中也起作用（如在帖子3中所述）。



      以下为原文

    And that's what we're different.
You think, I checked.
Two different programs. Both on the simulator and in silicon.

This "pseudo code" works in the configurations mentioned above (as also stated in post 3)
 
 

看我这个代码工作



      以下为原文

    Looks to me this code works

我不认为这是一个bug。XC32编译器通过XC的方式理解XC-PIC32 M.H中定义的“$0”作为寄存器“T0”。我相信你的“$T0”产生了你提到的断言。如果你加载我的例子，用“$T0”来注释这些行，你会看到一个错误。正如许多在线示例中提到的，使用“$t0”构造。



      以下为原文

   
I do not think this is a bug.
The xc32 compiler understands "$8" as register "t0" as defined in xc-pic32m.h by way of xc.h
I believe your "$ t0" produces the assertion you mention.
If you load my example and un comment the lines with "$ t0" you will see an error.
As I understand it the MIPS convention as mentioned in many online examples makes use of the "$ t0" construct.
It seems xc32 differs in this area.
 
 

首先，感谢您的技术响应。其次，我不认为问题是在寄存器的名称中。$T0（没有一个空间在某个地方的某个地方）是一个纯粹的汇编器名称，也用于简化，这样您就不必包括头文件。f项目中没有选项：项目属性-gt；xc32为-& gt；其他选项-gt；列表到文件附件中编译（但我使用xc非c32），但是当我启用这个选项时，它停止编译阿尔伯特



      以下为原文

    First of all, thank you for the technical response.
Secondly, I do not think the problem is in the names of registers.
$t0 (without a space that got somewhere along the way) is a purely assembler name, used also for simplicity so that you do not have to include header files.
Thirdly, in the settings of your project you do not have the option:
Project properties-> xc32-as-> other option-> List to file

Your attachment compiles  (but I use  XC not C32), but when I enable this option, it stops compiling
