For unknown reasons, Java 1.5 on 64-bit HP-UX 11.11 does signed computation of the new IAOQ value in the signal handler. In the current code these bits are not masked when returning to narrow mode, causing java to crash. Signed-off-by: Sven Schnelle --- target/hppa/sys_helper.c | 4 1 file

[PATCH 3/3] plugins/execlog: add address range matching

Allow to match memory ranges with the address matches. This allows to give a range of adresses like '-dfilter=0-0x400' which would only log memory accesses between 0 and 400. Signed-off-by: Sven Schnelle --- contrib/plugins/execlog.c | 73 ++- 1 fi

[PATCH 2/3] plugins/execlog: add data address match

Add a match similar to the afilter address match, but for data addresses. When an address is specified with '-dfilter=0x12345' only load/stores to/from address 0x12345 are printed. All other instructions are hidden. Signed-off-by: Sven Schnelle --- contrib/plugins/exec
