Re: [PATCH v2] libiberty, include: add bsearch_r

Hi Nick. libctf wants a bsearch that takes a void * arg pointer to avoid a nonportable use of __thread. bsearch_r is required, not optional, at this point because as far as I can see this obvious-sounding function is not implemented by anyone's libc. We can easily move

[COMMITTED 1/2] bpf: add support for the -mxbpf option

This patch adds support for a new option -mxbpf. This tells GCC to generate code for an expanded version of BPF that relaxes some of the restrictions imposed by BPF. 2020-05-19 Jose E. Marchesi gcc/ * config/bpf/bpf.opt (mxbpf): New option. * doc/invoke.texi (Option Summary

Re: GCC wwwdocs move to git done

Hi Joseph. I've done the move of GCC wwwdocs to git (using the previously posted and discussed scripts), including setting up the post-receive hook to do the same things previously covered by the old CVS hooks, and minimal updates to the web pages dealing with the CVS setup

Hi Gerald. I noticed that https://gcc.gnu.org does not have a news item related to this contribution. Would you mind adding one? (Our web pages are now in GIT, cf. https://gcc.gnu.org/about.html - let me know if you need help.) Done! :)

I think the bits are in good enough shape they can go in now. I just committed the port to svn trunk, in a single commit, yay! Many thanks to you, richard, seguer and the other reviewers for the great feedback and suggestions. What got committed is certainly WAY better than what I

Re: [PATCH V6 04/11] testsuite: new require effective target indirect_calls

This patch adds a new dg_require_effective_target procedure to the testsuite infrastructure: indirect_calls. This new function tells whether a target supports calls to non-constant call targets. This patch also annotates the tests in the gcc.c-torture testuite that

This patch annotates tests that make use of a significant a mount of stack space. Embedded and other restricted targets may have problems compiling and running these tests. Note that the annotations are in many cases not exact. As this implements a solution proposed by Jeff

Re: [PATCH V6 02/11] opt-functions.awk: fix comparison of limit, begin and end

The function integer_range_info makes sure that, if provided, the initial value fills in the especified range. However, it is necessary to convert the values to a numerical context before comparing, to make sure awk is using arithmetical order and not lexicographical order.
