Nonsences

天气晴 下午看到了天上的云有奇妙纹理，像脑花，掏出手机拍了一张，发现手机摄像头的马赛克效果比脑花纹理还清晰。 最近把主机转了个方向发现主板在 gprofng 编译的时候会亮过热的红灯，在cyy的建议下把 intel i7 12700 CPU 原装风扇换成了超大风扇，RISC-V qemu system 的性能好多了。既没有了终端显示乱刷问题，编译时间也快了很多。 本来之前 gprofng 没啥头绪的，现在貌似觉得还可以研究一下，因为可以根据报错来找到哪里有问题了。

目前成功构建的 patch ：RISC-V: Fix VL operand bug in VSETVL PASS[PR110264] 此patchRISC-V: Bugfix for RVV integer reduction in ZVE32/64.构建失败，但是RISC-V: Fix one typo for reduc expand GET_MODE_CLASS可以修复。 中间夹杂了 RISC-V:Add float16 tuple type support ,此构建失败报： ../.././gcc/gcc/rtl.h:316:31: warning: ‘rtx_def::mode’ is too small to hold all values of ‘enum machine_mode’ 316 | ENUM_BITFIELD(machine_mode) mode : 8;

近日办理业务发现了一年前签合同和协议踩的坑，记录一下，以后也会新增累积，成为游刃有余的老油条。 总结以下几条： 1.条款内容前后文矛盾 2.暗改合同日期 3.更换业务内容只签补充协议且执行按照合同正文日期 虽然签十个合同办理业务才可能出现这一个案例，但涉及金额较大业务时需要更加谨慎。不过更希望大家不会碰到这些事。 具体内容： 1.条款1写 4.15 - 4.18 是免租期。条款2写租金从4.15开始收取。实际免租期是个幌子。 2.约定租期1年，但是合同起止时间写 4.15 - 4.30。 3.网络合同正文写 4.15 ，但是发现宽带不符合办公要求时，办理电信业务租赁线路签补充协议不注明日期，实际执行按照合同正文。

天气雨 怎么还在摘樱桃。 发现想要根据报错来解决出现的问题的话就会出现本不该是 gcc 12 特性的 patch 被引入。 于是推倒重来，一个一个标记。 干的时候又很不耐烦，想要掏出脚本。不过还是不要太激进了，等编译的时候看看书。

天气晴。 早上到达武汉非常冷，发现了一个很中二的说法，回笼觉念成回龙决。 偷一个 /usr/include/sys/ucontext.h 出来观测，qemu 里面显示得太异常了。大佬告诉我这是 glibc 的内容。 /* struct ucontext definition, RISC-V version.
