Changes in directory llvm/lib/Bytecode/Writer:
SlotCalculator.cpp updated: 1.82 -> 1.83
SlotCalculator.h updated: 1.27 -> 1.28
Writer.cpp updated: 1.156 -> 1.157
---
Log message:
1. constants can never occur in the symbol table.
2. All function-level constants are now incorporated into the module-level
constant pool, since the compaction table was removed. Eliminate extra
work to check for them.
This speeds up the bcwriter from 24.4s to 13.1s on 447.dealII and .73 -> .56s
on kc++ in a release build.

The output bytecode file can be +another bytecode file or an executable bytecode program. Using additional +options, B is able to produce native code executables. + +The B tool is the main linker for LLVM. It is used to link together +the output of LLVM front-end compilers and run "link time" optimizations (mostly +the inter-procedural kind). + +The B tools attemps to mimic the interface provided by the default +system linker so that it can act as a I replacement. + +=head2 Search Order + +When looking for objects specified on the command line, B will search +for the object first in the current directory and then in the directory +specified by the B environment variable. If it cannot +find the object, it fails. + +When looking for a library specified with the B<-l> option, B first +attempts to load a file with that name from the current directory. If that +fails, it looks for libI.bc, libI.a, or libI.I, in that order, in each directory added to the library search +path with the B<-L> option. These directories are searched in the order they +are specified. If the library cannot be located, then B looks in the +directory specified by the B environment variable. If it +does not find a library there, it fails. + +The I may be I<.so>, I<.dyld>, I<.dll>, or something +different, depending upon the system. + +The B<-L> option is global.

Question: is it necessary to calculate ReadLatency up front rather
than calculated it on demand (i.e. the rest of the changes in this
file which use ReadLatency)?
Some nit picks.
1. Please pick identifiers that are more consistent with the rest of
the LLVM code. e.g. You'll find TID is used for TargetInstrDescriptor
all over the place.
2. Please use getUseIndex() instead of InstrSlots::Use.
3. Please "unsigned" instead of "char" for ReadLatency to match
getUseIndex(), etc.

Actually, please make each of these a public method. This provides
the ugly "X = X.udiv(Y)" syntax. Then add the namespace versions as
simple inline functions that that just call the method version.

[llvm-commits] llvm-gcc4: compile fix due to ParseBytecodeFile changes
"Read bytecodes from PCH file",
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070205/044159.html,
and "Push bytecode decompressor out through APIs",
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070205/044106.html,
passed each other in the night. The attached patch gets llvm-gcc4 building
again.
Ciao,
Duncan.

There's a lot of friend functions here. Perhaps these could go at the
bottom of the class declaration instead of the top.

Log message:
For PR1187: http://llvm.org/PR1187 :
Always rename, never give a redef error. We could check for collapsed type
planes and generate an error if that's not the cause, but the 99.
percentile case will be that its the result of collapsed type planes. So,
rather than doing an expensive check, just rename.

[llvm-commits] CVS: llvm/tools/llvm-upgrade/UpgradeParser.y
Changes in directory llvm/tools/llvm-upgrade:
UpgradeParser.y updated: 1.59 -> 1.60
---
Log message:
For PR1187: http://llvm.org/PR1187 :
Some changes to get the smbd.ll test case working:
1. Move the logic for CSRETCC->sret attribute out of the ResolveDefinitions
code and into getExistingValue. This resolves it much earlier and works
in function scope as well.
2. Fix handling of CSRETCC->sret for the store instruction.
3. Rewrite the code for handling renaming to factor in linkage types.
4. Rename a structure filed for a PATypeInfo* so it doesn't get confused
with a field for a Type*.
