- const README: rewrite the space-saving claim per issue #5 follow-ups (constant-expression const vs #define immediates; which const qualify as constant expressions) - const README: fix the class-section diagnosis per issue #338 (overload resolution picks the const overload; the restriction only surfaces once that overload is removed) - sizeof README: virtual-inheritance result is compiler-dependent (GCC merges vbptr+vfptr -> 16, MSVC keeps them separate -> 32) #246 - static README: new section on internal linkage / access restriction with anonymous-namespace comparison #142 - 10-day practice: full problem list table + fixed day links #136 - new design_pattern/singleton/singleton_default.hpp: reusable thread-safe CRTP singleton template, compile+concurrency tested #303

# Bazel 与 LLDB 联合调试
|
||
|
||
今天在调试时发现通过bazel编译出来的文件在mac上没法调试了，竟然全是汇编代码。
|
||
|
||
```
|
||
* thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1
|
||
frame #0: 0x0000000100000fd0 hello_world`main
|
||
hello_world`main:
|
||
-> 0x100000fd0 <+0>: pushq %rbp
|
||
0x100000fd1 <+1>: movq %rsp, %rbp
|
||
0x100000fd4 <+4>: subq $0x60, %rsp
|
||
0x100000fd8 <+8>: movl $0x0, -0x4(%rbp)
|
||
(lldb) quit
|
||
```
|
||
|
||
如何解决呢？
|
||
|
||
默认是standalone，我们需要disable，这里采用local，这意味着输出将与其依赖项链接，而不是采用默认的`standalone`策略。
|
||
|
||
```cpp
|
||
build --spawn_strategy=local
|
||
```
|
||
|
||
这样的话可以看到代码了。
|
||
|
||
```cpp
|
||
* thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1
|
||
frame #0: 0x0000000100000fdf hello_world`main at hello_world.cc:14:21
|
||
11
|
||
12 int main() {
|
||
13 // Create a thread pool
|
||
-> 14 auto threadPool = GetCpuThreadPool();
|
||
15 if (!threadPool) {
|
||
``` |
