Cargo subcommand to easily use LLVM source-based code coverage. This is a wrapper around rustc-C instrument-coverageand provides: Generate very precise coverage data. (line, region, and branch coverage. branch coverage is currently optional and requires nightly, see#8for more) ...
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=../install ../sourcecode/llvm -G选项,用于生成相关的makefile,具体情况请man一下 DCMAKE_BUILD_TYPE=Debug,用于生成Debug版本的安装包 DCMAKE_BUILD_TYPE=Release,用于生成Release版本的安装包,如果用这个选项,则4G的内存够也...

Bin Meng is from WindRiver. He is the senior R&D manager in VxWorks Department. Bin is very active tech promoter for RISC-V and other open source communities. MaskRay - Clang 的 gcov 实现 MaskRay - GCov implementations in Clang GCC提供 gcov 用于实现code coverage。本次主题浅析clang对它的兼容...
在上述命令中,-cc1选项告诉Clang使用底层编译器驱动程序,-emit-llvm选项告诉Clang生成LLVM字节码,-o source.bc指定生成的字节码文件名为source.bc,-x c指定输入源代码类型为C语言。 总结来说,clang -c是用于将源代码编译为目标文件的简化选项,而clang -cc1是Clang底层编译器驱动程序的选项,用于手动控制编译...
This is something I've wanted to do for some time, but I haven't had the time. I'll use this issue to write down some of the issues that need to be solved. If someone has the time to address this feel free to open a PR. Source-based cove...
EmitBCAction - 生成 IR Bitcode 文件,option 是 -emit-llvm-bc MigrateSourceAction - 代码迁移,option 是 -migrate Bind Bind 主要是与工具链 ToolChain 交互 根据创建的那些 Action,在 Action 执行时 Bind 来提供使用哪些工具,比如生成汇编时是使用内嵌的还是 GNU 的,还是其它的呢,这个就是由 Bind 来决定的...
