Summary: huge memory consumption when compiling simple repetitive
programs
Product: gcc
Version: 3.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: bjg at network-theory dot co dot uk
CC: gcc-bugs at gcc dot gnu dot org
GCC build triplet: i686-pc-linux-gnu
GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu
C programs which consist of simple repeated function calls cause
gcc to consume huge amounts of memory with -O2. For example,
a single program containing 2000 calls to another function
requires a peak 90 megabytes of memory to compile (attached
below). A similar 4000 line program requires over 350
megabytes. These types of program are common in
auto-generated test suites. This was encountered in the test
suite for GSL (GNU Scientific Library).
Environment:
System: Linux debian 2.4.19 #16 Wed May 21 09:48:43 BST 2003 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu

How-To-Repeat:
No headers are needed to demonstrate this problem, and linking is not
required, so a plain .c file has been supplied.

Can you provide the source code as it looks like it did not get attached (looks again gccbug did not
do its job)?

------- Additional Comments From pinskia at gcc dot gnu dot org 2003-08-13 12:30 -------
I can confirm this on the mainline (20030811). It is the schedular which causes this memory
consumption using -fno-schedule-insns and -fno-schedule-insns2 will get rid of this memory
consumption.
