I just got this on the vim-dev list. If this is indeed so (strip does not work on s390) does that mean Debian policy forces us to have large unstripped binaries on s390?
Wichert. ----- Forwarded message from Anthony Giorgio <[EMAIL PROTECTED]> ----- From: "Anthony Giorgio" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Excessive size of s390 vim binary Date: Wed, 19 Sep 2001 10:37:56 -0400 When vim is built on an IBM s390 mainframe, the size of the binary is much larger than it needs to be. This is due to the symbolics information remaining within the binary, since it is compiled with the -g flag. On a standard Unix/Linux system this is fine, as one can strip(1) a binary to remove the debugging info. On an s390 system, strip is identical to touch(1), and cannot remove the symbols from the file. Here's an excerpt from the strip man page: | strip -- Remove unnecessary information from an executable file Format strip file | Description | On some UNIX systems, strip removes debug information from an executable. | On z/OS, the debug information can only be removed by recompiling. strip | does not modify the contents of any executable file--it is functionally | equivalent to touch file. We should change the default behavior of the Makefile to not generate the debugging information. I propose that the makefile on s390 be altered to remove the -g flag from CFLAGS. Replacing -g with -0 (zero) dramtically reduces the size of the binary. It shrinks from 5853184 bytes to 2052096 bytes, a 65% reduction. What do you all say? On a different note, any optimizations I turn on (-1 or -2) for the compiler causes vim to commit a segmentation violation as soon as it is invoked.
