Changes in directory llvm/docs:
BytecodeFormat.html updated: 1.52 -> 1.53 LangRef.html updated: 1.156 -> 1.157 --- Log message: Adding dllimport, dllexport and external weak linkage types. DLL* linkages got full (I hope) codegeneration support in C & both x86 assembler backends. External weak linkage added for future use, we don't provide any codegeneration, etc. support for it. --- Diffs of the changes: (+46 -8) BytecodeFormat.html | 23 ++++++++++++++++------- LangRef.html | 31 ++++++++++++++++++++++++++++++- 2 files changed, 46 insertions(+), 8 deletions(-) Index: llvm/docs/BytecodeFormat.html diff -u llvm/docs/BytecodeFormat.html:1.52 llvm/docs/BytecodeFormat.html:1.53 --- llvm/docs/BytecodeFormat.html:1.52 Thu Apr 20 00:05:12 2006 +++ llvm/docs/BytecodeFormat.html Thu Sep 14 13:23:26 2006 @@ -1025,7 +1025,8 @@ <tr> <td><a href="#bit">bit(2-4)</a></td> <td class="td_left">Linkage type: 0=External, 1=Weak, -2=Appending, 3=Internal, 4=LinkOnce</td> + 2=Appending, 3=Internal, 4=LinkOnce, 5=DllImport, + 6=DllExport, 7=ExternWeak</td> </tr> <tr> <td><a href="#bit">bit(5-31)</a></td> @@ -1136,13 +1137,16 @@ <td><a href="#bit">bit(4)</a></td> <td class="td_left">If this bit is set to 1, the indicated function is external, and there is no <a href="#functiondefs">Function Definiton - Block</a> in the bytecode file for the function.</td> + Block</a> in the bytecode file for the function.
