Raymond Toy pushed to branch rtoy-issue-76-add-ansi-tests-to-ci at cmucl / cmucl Commits: 00679e6b by Raymond Toy at 2020-08-25T22:05:21-07:00 Fix #84: Remove code/unix-glibc2.lisp This isn't referenced in worldcom or worldbuild anymore so we can safely remove this. Most of the required functionality was moved to code/unix.lisp some time ago, so this isn't needed anymore. Whatever functionality that is still left is in contrib/unix/unix-glibc2.lisp, which we aren't removing. - - - - - 60d0d7bb by Raymond Toy at 2020-08-26T05:15:09+00:00 Merge branch 'rtoy-issue-84-remove-unix-glibc2' into 'master' Fix #84: Remove code/unix-glibc2.lisp Closes #84 See merge request cmucl/cmucl!51 - - - - - 449f8ec1 by Raymond Toy at 2020-08-26T17:09:13-07:00 Fix #85: Let each x86 configs set optimization level Add `COPT` variable in `Config.x86_common` to set the optimization level (defaulting to `-O2`). Then each `Config.x86` file can set `COPT` as desired if the default doesn't work. Thus, `Config.x86_linux` sets `COPT` to `-O1`, but others can use the default value.

This is necessary to be able to read/write/stat files that -;; are larger than 2GB on a 32-bit system. From a C program, defining -;; a preprocessor macro _LARGEFILE64_SOURCE makes the preproccessor -;; replace a call to open() by open64(), and similarly for stat, -;; fstat, lstat, lseek, readdir and friends. Furthermore, certain data -;; types, that are normally 32 bits wide, are replaced by 64-bit wide -;; equivalents: off_t -> off64_t etc. The libc.so fiddles around with -;; weak symbols to support this mess. -;; -;; From CMUCL, we make FFI calls to the xxx64 functions, and use the -;; 64-bit wide versions of the data structures. The most ugly aspect -;; is that some of the stat functions are not available via dlsym, so -;; we reference them explicitly from linux-stubs.S. Another amusing -;; fact is that on glibc 2.2, stat64() returns a struct stat with a -;; 32-bit ino_t, whereas readdir64() returns a struct dirent that -;; contains a 64-bit ino_t. On glibc 2.1, OTOH, both stat64 and -;; readdir64 use structs with 32-bit ino_t. -;; -;; The current version deals with this by going with the glibc 2.2 -;; definitions, unless the keyword :glibc2.1 also occurs on *features*, -;; in addition to :glibc2, in which case we go with the glibc 2.1 -;; definitions. Note that binaries compiled against glibc 2.1 do in -;; fact work fine on glibc 2.2, because readdir64 is available in both -;; glibc 2.1 and glibc 2.2 versions in glibc 2.2, disambiguated through -;; ELF symbol versioning.
