which is evaluated slightly differently than in previous versions of gcc. arch/alpha/alpha_linux_process.cc: Alphabetize includes. arch/alpha/vptr.hh: Change the constants that are being used for alpha pagebytes to come from the ISA. base/random.hh: cpu/static_inst.cc: sim/param.cc: Fix up template syntax. base/range.hh: Include iostream for << operator. base/res_list.hh: base/statistics.hh: cpu/simple_cpu/simple_cpu.hh: cpu/static_inst.hh: sim/eventq.hh: sim/param.hh: Fixup for templated code to resolve different scope lookup in gcc 3.4. This defers the lookup of the function/variable until actual instantiation time by making it dependent on the templated class/function. base/trace.cc: Fix call to new. base/trace.hh: Fix up #define to have full path. cpu/base_cpu.cc: Fix up call to new. dev/etherlink.hh: dev/ns_gige.hh: dev/sinic.hh: Fixup for friend class/function declaration. g++ 3.4 no longer allows typedefs to be declared as a friend class. dev/pcidev.hh: Fix up re-definition of access level to params. kern/linux/linux_syscalls.hh: kern/tru64/tru64_syscalls.hh: Fix up header. Fix up template syntax. sim/serialize.cc: Include errno.h. sim/startup.cc: Change startupq. queue was getting destructed before all things had called ~StartupCallback(), which lead to a segfault. This puts startupq in global space, and we allocate it ourselves. Other code may be similar to this and may need changing in the future. sim/syscall_emul.hh: Include cpu/exec_context.hh and sim/process.hh, as forward declarations are no longer sufficient. sim/universe.cc: Include errno.h --HG-- extra : convert_revision : e49d08ee89eb06a28351f02bafc028ca6652d5af
