From mboxrd@z Thu Jan 1 00:00:00 1970 From: Zou Min To: GCC ML Subject: Question about memory usage difference Date: Mon, 15 Oct 2001 23:44:00 -0000 Message-id: <20011016144314.A20549@comp.nus.edu.sg> X-SW-Source: 2001-10/msg00890.html Dear all, I am using RH7.1 with glibc-2.2.2-10. I installed both gcc-2.95.3 and gcc-2.91 (egcs-1.1.2). I know there is a big change from gcc-2.91 to gcc-2.95.3. I tried to use both of them to compile set of source files. I found that the number of disk reads are larger when memory size decreases when using gcc-2.95.3. Is that because in gcc-2.95.3, the developers tried to reduce memory requirement in a way that caused more disk caches reserverd? (just a tentative guess) Anyway, can some body tell me how the memory usage differs between gcc-2.95.3 and gcc-2.91 when compiling the same source? Or, anywhere I can find out the related information? or which part of the source code should I look for? Thanks a lot! -- Cheers! Zou Min
