[lldb] Fix TestDyldExecLinux with xml enabled 2022-06-14T09:44:59+00:00 Pavel Labath pavel@labath.sk 2022-06-14T09:38:45+00:00 cf2c8e419dbc6575f82b8ac44b62a2306624899a NativeProcessLinux is not able to properly read libraries-svr4 data when running with ld.so as the "main" executable. Normally, this is not a big problem, as it returns an error message, and lldb can fallback to manual library loading. Unfortunately, lldb-server also does not clear cached svr4 data on exec, which means that it does *not* return an error when the application execs from the "regular" to the "ld.so" mode. Instead it returns incorrect data (it is missing the main executable) and causes TestDyldExecLinux to fail (but only when building with xml support enabled). This patch makes ensures that cached process data is cleared on exec, fixing the test. Since TestDyldExecLinux has shown to be sensitive to the way we read library info, I fork it into two (with svr4 enabled and disabled).

Add the ability to debug through an exec into ld 2022-05-09T23:07:40+00:00 Greg Clayton gclayton@fb.com 2022-05-09T18:48:18+00:00 879a47a55ffb94976cbac1d191ef53be135d86a7 A previous commit enabled LLDB to be able to debug a program launched via ld: https://reviews.llvm.org/D108061. This commit adds the ability to debug a program launched via ld when it happens during an exec into the dynamic loader. There was an issue where after the exec we would locate the rendezvous structure right away but it didn't contain any valid values and we would try to set the dyanamic loader breakpoint at address zero. This patch fixes that and adds a test. Differential Revision: https://reviews.llvm.org/D125253
