[LLVMdev] Benchmarks

Dear List,

There's been some recent discussion on the list about benchmarks. I just
read a Dr. Dobbs article on the relative runtime performance of various
compilers (8 of them compared) on Intel platforms. The test focused on
mainly template type things but offers Dhrystone and zlib for
comparisons.

There's no clear winner as all compilers perform well in some areas and
poorly in others. The overall rating (Table 2 in the article) ranks the
compilers thusly (higher is better):

Intel 8.0	9.22
VC++ 7.1	7.56
CodeWarrior	7.44
GCC 3.2		6.67
VC++ 6.0	6.00
Comeau 4.3.3	4.56
Borland 5.6.4	3.78
Open Watcom 1.2	3.00

I am, of course, curious how LLVM stacks up in both native code
generation and the CBE. I guess the main point is that GCC is not the
compiler to beat, Intel 8.0 is (at least for the template based tests
this benchmark was aimed at). Any chance we can get this test suite
included in the benchmark?

You can find the article online here:

but you'll need to register.
