fix formatting

return a pointer to the end of the valid part of the sigstack, no further

also unmap the whole thing when cleaning up, rather than leaving a spare page floating around.

unix: Set a guard page at the end of signal stacks

2020-03-13T03:32:02+00:00

This mitigates possible issues when signal stacks overflow, which could manifest as segfaults or in unlucky circumstances possible clobbering of other memory values as stack overflows tend to enable.

unix: Don't override existing SIGSEGV/BUS handlers

2020-03-09T01:44:12+00:00

Although `stack_overflow::init` runs very early in the process, even before `main`, there may already be signal handlers installed for things like the address sanitizer. In that case, just leave it alone, and don't bother trying to allocate our own signal stacks either.

Format libstd/sys with rustfmt

2019-11-30T02:37:58+00:00

This commit applies rustfmt with rust-lang/rust's default settings to files in src/libstd/sys *that are not involved in any currently open PR* to minimize merge conflicts. THe list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in outstanding_files, the relevant commands were: $ find src/libstd/sys -name '*.rs' \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ rg libstd/sys outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of the files. To confirm no funny business: $ git checkout $THIS_COMMIT^ $ git show --pretty= --name-only $THIS_COMMIT \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ git diff $THIS_COMMIT # there should be no difference
