[Lldb-commits] [PATCH] D61210: [lldb] [lit] Introduce tests for reading x86 general purpose registers

[Michał Górny via Phabricator via lldb-commits]

mgorny added a comment.

GCC refuses to build this with:

  Inputs/x86-64-gp-read.cpp: In function ‘int main()’:
  Inputs/x86-64-gp-read.cpp:31:1: error: bp cannot be used in asm here
   }
   ^
  Inputs/x86-gp-read.cpp: In function ‘int main()’:
  Inputs/x86-gp-read.cpp:31:1: error: bp cannot be used in asm here
   }
   ^

Clang doesn't complain but it also seems to generally exhibit special assumptions about *bp not being touched by assembly. In this particular case, it seems to generate correct code (with push/pop for rbp around my code).
