2005-01-12Fix sign extend to long. When coming from sbyte, we used to generate:Chris Lattner
movsbl 4(%esp), %eax movl %eax, %edx sarl $7, %edx Now we generate: movsbl 4(%esp), %eax movl %eax, %edx sarl $31, %edx Which is right. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19515 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-11Comment out debug code :)Chris Lattner
Select [mem] += Val operations. For constants, we used to get: mov %ECX, -32768 add %ECX, DWORD PTR [l4_match_start] mov DWORD PTR [l4_match_start], %ECX Now we get: add DWORD PTR [l4_match_start], -32768 For other values we used to get: mov %EBP, %EDI ;; because the add destroys the value add %EBP, DWORD PTR [l4_input_len] mov DWORD PTR [l4_input_len], %EBP now we get: add DWORD PTR [l4_input_len], %EDI Both of these use less registers than the alternative, are faster and smaller. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19488 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-11Implement the LOADABLE_MODULE option when building a shared library. ThisReid Spencer
passes the -module option on the libtool command line to ensure that the shared library being built can be dlopened and dlsym can work on that module. LOADABLE_MODULE should be sent only in conjunction with the SHARED_LIBRARY directive. It should generally be used for any module that is intended to be the target of an LLVM -load option. Note that loadable modules will not have the lib prefix but otherwise look like shared libraries. This is per the libtool recommendations and prevents these special shared libraries from being linked in via -l option to the linker. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19454 91177308-0d34-0410-b5e6-96231b3b80d8
