Summary: [3.3.2 regression] Huge memory use while compiling a C
file
Product: gcc
Version: 3.3.2
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: casteyde dot christian at free dot fr
CC: gcc-bugs at gcc dot gnu dot org
GCC build triplet: i686-pc-gnu-linux
GCC host triplet: i686-pc-gnu-linux
GCC target triplet: i686-pc-gnu-linux
While compiling Cinelerra, the file "quicktime/cmodel_default.c"
makes gcc eats nearly 512Mo RAM. This doesn't happen with gcc 3.3.1
(but cinelerra builds finally, whereas it didn't build with gcc 3.3.1).
This doesn't happen without optimization flags used by the build
system either. Preprocessed source and faulty flags appended.
To reproduice : compile with
gcc -c `cat flags` az.c

I fail to see any regression from 3.3.1 to current 3.3 branch (20031107). It looks like the loop
optimizer is taking the biggest chunk of time, but still, under 1/3 of total compile time. Using
flags -O3 -funroll-all-loops, the whole things takes around 120 seconds, 500 megs. With only -
O3, it gets aways with 70 seconds and 400 megs. On mainline it's even worse: 205 seconds for
only -O3. I'll see if I can shrink the code a bit for a better testcase...

This is a loop optimizer issue. For me it already terminates with "-O2
-funroll-all-loops -fno-unit-at-a-time".
