* [Bug gdb/18077] New: Using -exec-run with mi-async on results in synchronous execution @ 2015-03-03 16:26 simon.marchi at ericsson dot com 2015-03-03 16:26 ` [Bug gdb/18077] " simon.marchi at ericsson dot com ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: simon.marchi at ericsson dot com @ 2015-03-03 16:26 UTC (permalink / raw) To: gdb-prs https://sourceware.org/bugzilla/show_bug.cgi?id=18077 Bug ID: 18077 Summary: Using -exec-run with mi-async on results in synchronous execution Product: gdb Version: HEAD Status: NEW Severity: normal Priority: P2 Component: gdb Assignee: unassigned at sourceware dot org Reporter: simon.marchi at ericsson dot com Using this simple test program: int main() { for (;;); return 0; } And trying these commands: $ gdb -nx -i mi a.out -gdb-set mi-async on -exec-run -exec-interrupt --all <--- It doesn't work, even though it should since we are in mi-async on mode. I traced the root of the problem to this line: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=gdb/mi/mi-main.c;h=7412f7d8a553ca6739da1480c2e84572f38a8e78;hb=HEAD#l493 At this point, the linux-native run target is not pushed yet. mi_async_p ends up calling tdefault_can_async, which returns false, so we don't execute asynchronously. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread

It passes when I replace the return 0 in tdefault_can_async_p by return 1. It's obviously not the right solution, but I think it shows what the behaviour should be on linux-nat. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread
