Subject: Fix length arg in call to breakpoint_xfer_memory.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c63528fc47c79721b55f32fe1649762ff9125ae0;p=binutils-gdb.git

Fix length arg in call to breakpoint_xfer_memory.

The patch "return target_xfer_status in to_xfer_partial" caused a
regression in various s390(x) test cases, because memory_xfer_partial
filled only the first byte of the read buffer from a breakpoint shadow:

This patch fixes the regression.
