Folks,<BR>
<BR>
Here's some timing results looking at LLVM when it uses libLLVMCore.o vs. libLLVMCore.a. We're trying to decide which way to go and thought some data would help. The data below was generated from using GCC 3.4.6 and binutils 2.15.92 on Fedora Core 3 running on a 2.4GHz Dual Xenon with 1GB of ram.<BR>
