我想知道为什么LLVM_website上的llvm-bcanalyzer帮助页面和我正在使用的当前v3.8之间存在很多不匹配。我已使用v3.0和v3.4检查了它们，但没有一个是一致的。
其次，显然无论我传递的是什么[选项]，输出都是一样的。
例如，这是v3.8的可用选项：
OVERVIEW: llvm-bcanalyzer file analyzer
USAGE: llvm-bcanalyzer [options] <input bitcode>
OPTIONS:
General options:
-block-info=<string> - Use the BLOCK_INFO from the given file
-disable-histogram - Do not print per-code histogram
-dump - Dump low level bitcode trace
-non-symbolic - Emit numeric info in dump even if symbolic info is available
-show-binary-blobs - Print binary blobs using hex escapes
Generic Options:
-help - Display available options (-help-hidden for more)
-help-list - Display list of available options (-help-list-hidden for more)
-version - Display the version of this program
看，字面上没有关于v3.4的内容：
llvm-bcanalyzer-3.0 llvm-bcanalyzer-3.4
ashouri@gbomb:~$ llvm-bcanalyzer-3.4 --help
OVERVIEW: llvm-bcanalyzer file analyzer
USAGE: llvm-bcanalyzer-3.4 [options] <input bitcode>
OPTIONS:

...
这两个与网站上的不同！
我想获得写在llvm-bcanalyzer上的输出。谁能帮我？这些信息对我来说很有价值。
