+pThe packed structure type is used to represent a collection of data members
+together in memory. There is no padding between fields. Further, the
alignment
+of a packed structure is 1 byte. The elements of a packed structure may
+be any type that has a size./p
+pStructures are accessed using 'tta href=#i_loadload/a/tt
+and 'tta href=#i_storestore/a/tt' by getting a pointer to a
+field with the 'tta href=#i_getelementptrgetelementptr/a/tt'

[llvm-commits] CVS: llvm/docs/BytecodeFormat.html LangRef.html
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 tda href=#bitbit(2-4)/a/td td class=td_leftLinkage 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 tda href=#bitbit(5-31)/a/td @@ -1136,13 +1137,16 @@ tda href=#bitbit(4)/a/td td class=td_leftIf this bit is set to 1, the indicated function is external, and there is no a href=#functiondefsFunction Definiton - Block/a in the bytecode file for the function./td + Block/a in the bytecode file for the function.
