gcc: update to allow compiling different versions This is based on the toolchain GCC, and aims to share as much of its Makefile and patches with that definition. The package requires two additional patches: (1) 003-dont-choke-when-building-32bit-on-64bit.patch, which fixes the `error: size of array 'test_real_width' is negative` error that occurs when building a 32-bit GCC on a 64-bit host. (Search the Internet for examples of this error appearing.) (2) 980-add-nostdinc++.patch, which backports a fix from 11.3.0 (11.2.0 only). Signed-off-by: W. Michael Petullo <mike@flyn.org> (cherry picked from commit ceaa6e840e0b57c1b47c784997187044e3311d23)

  1. From dda6b050cd74a352670787a294596a9c56c21327 Mon Sep 17 00:00:00 2001

  4. Subject: [PATCH] gotools: fix compilation when making cross compiler
  5. 

  6. libgo is "the runtime support library for the Go programming language.
  7. This library is intended for use with the Go frontend."
  8. 

  9. gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
  10. the linker will complain that it cannot find it.  That's because shared libgcc
  11. is not present in the install directory yet.  libgo.so was made without problem
  12. because gcc will emit -lgcc_s when compiled with -shared option.  When gotools
  13. were being made, it was supplied with -static-libgcc thus no link option was
  14. provided.  Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
  15. for linking with libgo.so
  16. 

  17. - GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation

  18. - Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html

  19. 

  20. When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
  21. available after gcc pass2 completed and will meet the gotools link requirement
  22. at gcc pass3
