From: Mike Frysinger Date: Sat, 24 Apr 2021 18:35:14 +0000 (-0400) Subject: sim: callback: convert time interface to 64-bit X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=00330cd18a4ba83beabad4cb9f4215170828cd29;p=binutils-gdb.git sim: callback: convert time interface to 64-bit PR sim/27705 Rather than rely on time_t being the right size between the host & target, have the interface always be 64-bit. We can figure out if we need to truncate when actually outputting it to the right target. --- diff --git a/include/sim/ChangeLog b/include/sim/ChangeLog index a70d8f06cf2..393b7b8262e 100644 --- a/include/sim/ChangeLog +++ b/include/sim/ChangeLog @@ -1,3 +1,9 @@ +2021-05-14 Mike Frysinger + + * callback.h: Include stdint.h. + (struct host_callback_struct): Change time return to int64_t.
