-mllvm指定将后一个选项传递给llvm. 因为默认执行的clang其实是一个driver, 在运行中调用对应的程序执行前端分析(clang), 中端优化指令选择(llvm)以及汇编链接(assembler & linker). -debug选项即将llvm中DEBUG宏输出到stderr. 如果我们只想需要某个特定pass的打印可以使用-debug-only选项(后接pass的DEBUG_TYPE). ...
如果一切顺利的话,你就能在Debug+Asserts/lib/下看到新生成的DeadBlock.so了。 就来用一开始提到的示例IR作为测试代码好了,用LLVM自带的assembler来编译IR到bytecode: llvm-as test.ll 然后,我们用LLVM自带的opt工具来动态载入新pass并执行。重新进到<你的LLVM安装目录>/lib/Transforms/DeadBlock下: opt -load ...
In looking at the assembler code, I think one can convert it into a arguable iterative process. Here is my thought (not tested in code) On entry to ack: you copy %esp to %ecx (or rcx when coding x64) After that you add tag ack_loop: Replace the "call ack" ...
As the Makefile enables the debug option -g (LLVM version >= 4.0), the llvm-objdump tool can annotate assembler output with the original C code: Run: llvm-objdump -S xdp_pass_kern.o xdp_pass_kern.o: file format ELF64-BPF Disassembly of section xdp: xdp_prog_simple: ; { 0: b7 ...
Both PTX and the target assembler code use the format <instruction> <target_reg> <source_reg1> <source_reg2> The PTX code is extensively documented in the PTX ISA found in the “doc” directory of the NVIDIA GPU Computing Toolkit as the “ptx_isa_3.0.pdf” file for the CUDA 4.1 SDK...

All of the test routines were rewritten in assembler to improve both error detection and speed. A progress meter was added to show pass and test completion. The screen layout was reworked to hopefully be more readable. Support for creating BadRAM patterns was added. (Code was provided by Rick...
Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer. C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM. Other components include: ...
