[LLVMdev] really long time to compile
Hi,
Can anyone suggest any reasons why this seemingly-innocuous (though
stupid-looking) excerpt from gnu fileutils 4.1 would make llvm-gcc
go so incredibly slowly? It doesn't seem to be a question of the
size of the output.
Here's what I do:
% time llvm-gcc -c sha24.c
56.840u 0.050s 1:07.05 84.8% 0+0k 0+0io 1050pf+0w
% ls -l sha24.o
-rw-r--r-- 1 brg brg 5784 2002-12-14 07:43 sha24.o
The problem goes away if I use -S:
% time llvm-gcc -S sha24.c
0.060u 0.010s 0:00.09 77.7% 0+0k 0+0io 548pf+0w
