[LLVMdev] darwin dragon-egg build issues

[Jack Howarth]

Duncan,
    Do a quick check here on x86_64-apple-darwin10
with svn llvm and svn dragon-egg against release gcc 4.5.0,
the results from the himenoBMTxpa benchmark compiled at -O3
look pretty good. With stock gcc-4.5.0, we get...

Grid-size = M

mimax = 128 mjmax = 128 mkmax = 256
imax = 127 jmax = 127 kmax =255
 Start rehearsal measurement process.
 Measure the performance in 3 times.

 MFLOPS: 156.560865 time(s): 2.575476 1.733593e-03

 Now, start the actual measurement process.
 The loop will be excuted in 69 times
 This will take about one minute.
 Wait for a while

 Loop executed for 69 times
 Gosa : 1.449961e-03 
 MFLOPS measured : 156.771134	cpu : 59.156498
 Score based on Pentium III 600MHz using Fortran 77: 1.911843

and for the same through the plugin we get...

 Now, start the actual measurement process.
 The loop will be excuted in 67 times
 This will take about one minute.

So dragon-egg is less than 5% slower.
