Web实际调试中经常需要调查函数使用的变量的值。要在kprobes的侦测器内显示某个函数的局部变量的值,需要一些技巧,原因是在printk的参数中无法直接指定变量名,因此必须给侦测器函数提供一个pt_regs结构,其中保存了指定地址的命令执行时的寄存器信息。. 当然,不同架构下该结构的成员变量不尽 ...

[PATCH 3/5][Arm] New pattern for CSINC instructions

WebNov 22, 2024 · Commits rG5c64d8ef8cc0: [ARM] CSINC/CSINV patterns from CMOV Summary We sometimes end up generating CMOV with constant operands that can be simplified to CSINC or CSINV under Arm-8.1m. This adds some simple patterns for them. Diff Detail Repository rG LLVM Github Monorepo dmgreen created this revision. Nov 22 … WebSimilarly for the CSINV and CSINC instructions, they have shorter CINV and CINC forms. This patch adjusts the output templates to emit the preferred shorter sequences when possible. The new mnemonics are just aliases, they map down to the same instruction in the end, so there are no performance or behaviour implications. phil senior football https://prediabetglobal.com
