read_frame_register_value and big endian arches The read_frame_register_value function as it was implemented introduced a regression on big-endian targets. The problem appears when trying to get the value of an entity stored inside a register, and when the size of the entity is smaller than the size of the register. In that case, we were always reading the first N bytes of the register, which is wrong for big-endian architectures, where we need to read the last N bytes of the register. gdb/ChangeLog: * findvar.c (read_frame_register_value): Read correct bytes from register on big-endian architectures. gdb/testsuite/ChangeLog: * gdb.ada/small_reg_param: New testcase.

Fix FAIL: gdb.ada/small_reg_param.exp: continue to call_me If enough information is provided by the compiler, the debugger now prints the entry value of various parameters: (gdb) continue Continuing. Breakpoint 2, pck.call_me (w=w@entry=50) at [...] 20 Last_Word := W; This patch adjusts the expected output to allow an optional "w@entry=" in the parameter value. gdb/testsuite/ChangeLog: * gdb.ada/small_reg_param.exp: Accept optional entry value for parameter "w".
