Description I'm attempting to unroll a fixed-size scalar search loop so that it will generate a chain of cmovs. It's possible to get this to happen in C compiled by clang and msvc, but not C# on .NET 9. Instead, the best-case is a chain ofmovzx; cmp; jne; movopcode clusters,...

在Flow Navigator中,确保 HLS 组件处于活动状态,或者在Component(组件)菜单中将其选中,在该工具中将其设为活动组件。当 HLS 组件为活动组件时,Flow Navigator支持运行 C 语言仿真、C 语言综合、C/RTL 协同仿真、封装与实现来构建和分析该 HLS 组件。要综合 HLS 组件,
csim 选项适用于 C 语言仿真进程,此进程用于确认设计的 C/C++ 语言。如需了解更多信息,请参阅 Vitis 高层次综合用户指南(UG1399) 的“运行 C 语言仿真”部分。 csim.O 启用优化编译,以消除调试构造。默认情况下为 false 且以调试模式执行编译以启用调试。 csim.O=true cs
