Though after posting, I noticed that version had a placement typo: I put the "sleep" entry right after "alarm", before "c" (it's kind-of related to alarm). I moved it to a "better" position regarding alphabetization as per below as obvious: committed. The list has some stray entries or non-linear sequences, but at least I didn't introduce any more out-of-order terms. Tested for cris-elf with the-other-patch (awaiting review) and sanity-checked on host x86-linux and viewed the resulting gccint.info. brgds, H-P -- >8 -- From: Hans-Peter Nilsson <[email protected]> Subject: [PATCH 1/2] testsuite: New effective-target sleep libgfortran calls sleep, which is not available on all targets. gcc: * doc/sourcebuild.texi (Effective-Target Keywords): Document 'sleep'. gcc/testsuite: * lib/target-supports.exp (check_effective_target_sleep): New. --- gcc/doc/sourcebuild.texi | 3 +++ gcc/testsuite/lib/target-supports.exp | 13 ++++++++++++- 2 files changed, 15 insertions(+), 1 deletion(-) diff --git a/gcc/doc/sourcebuild.texi b/gcc/doc/sourcebuild.texi index 3bccb1384d9f..0bfcb96814d8 100644 --- a/gcc/doc/sourcebuild.texi +++ b/gcc/doc/sourcebuild.texi @@ -2936,6 +2936,9 @@ Target can compile using @code{pthread.h} with no errors or warnings. @item pthread_h Target has @code{pthread.h}. +@item sleep +Target supports @code{sleep}. + @item sockets Target can compile using @code{sys/socket.h} with no errors or warnings. diff --git a/gcc/testsuite/lib/target-supports.exp b/gcc/testsuite/lib/target-supports.exp index e7165e2e1b8c..bf00572e2bc6 100644 --- a/gcc/testsuite/lib/target-supports.exp +++ b/gcc/testsuite/lib/target-supports.exp @@ -14823,6 +14823,17 @@ proc check_effective_target_alarm { } { }] } +# Return true if sleep is supported on the target. + +proc check_effective_target_sleep { } { + return [check_no_compiler_messages sleep executable { + #include <unistd.h> + int main (void) { + sleep (1); + } + }] +} + # Return true if a speculation barrier is defined on the target. proc check_effective_target_speculation_barrier_defined { } { return [check_no_compiler_messages speculation_barrier_defined assembly { -- 2.30.2
