通常所说的GCC是GUN Compiler Collection的简称,是Linux系统上常用的编译工具。GCC实质上不是一个单独的程序,而是多个程序的集合,因此通常称为GCC工具链。工具链软件包括GCC、C运行库、Binutils、GDB等。 GCC GCC(GNU C Compiler)是编译工具。本文所要介绍的将C/C++语言编写的程序转换成为处理器能够执行的二进制代码...
ABI strings are concatenated together and passed via the-mabiargument to GCC. For example: -march=rv32imafdc -mabi=ilp32d: Hardware floating-point instructions can be generated and floating-point arguments are passed in registers. This is like the-mfloat-abi=hardoption to Arm’s GCC. 架构支...

Linux toolchain has an additional option--enable-default-pieto control the default PIE enablement for GCC, which is disable by default. To customize the enabled languages, use option--with-languages=. For example, if you want to enablec,c++,fortran, use./configure --with-languages=c,c++,for...
最后他又比较了Embench在不同的Architecture， 以及不同的GCC Option下的Code Size，如下图所示。很明显ARM还是有一定优势的，不过Patterson也指出过去几年RISC-V GCC 的进步也不小，和ARM的差距在不断地缩小。对此，我有一点小小的想法，如果用ArmCC而不是GCC来在ARM上跑Embench，那RISC-V和ARM的差距会不会更大...

Then, enter the directory and turn off every configuration option:$ cd busybox-1.26.2 $ make allnoconfig We will need to change the cross-compiler, set the build to "static" (if desired, you can make it dynamic, but you'll have to copy some libraries later). We will also enable ...
riscv cross compiler error: invalid -march= option: `rv64imafdc_zicsr' I'm new to the world of gcc. I don't know if this is the right place to post, but I'm having some issues that are really annoying. I've created a Unix-like system, and although it's not very complete ....
[51] The plan is that these can reduce the size and complexity of the ISA and compiler.[51] 参考译文:向量长度不仅是架构上可变的,而且设计为在运行时也可变。为了实现这种灵活性,指令集可能会使用可变宽度的数据路径和多态重载的可变类型操作。这些可以减少ISA和编译器的大小和复杂性。 Recent experimental...
