Hotspot Coding Style

...

• Conform new code to style conventions. Avoid unnecessary "esthetic" variations, which are distracting.
• Use the C++ RAII design pattern to manage bracketed critical sections. See class ResourceMark for an example.
• +Verbose is used to provide additional output for another flag, but does not enable output by itself.
• Do not use ints or pointers as booleans with &&, ||, if, while. Instead, compare explicitly != 0 or != NULL, etc. (See #8 above.)
• Use functions from globalDefinitions.hpp when performing bitwise operations on integers. Do not code directly as C operators, unless they are extremely simple. (Examples: round_to, is_power_of_2, exact_log2.)
• Naming JTreg tests
• More suggestions on factoring.

• Do not put non-trivial function implementations in .hpp files. If the implementation depends on other .hpp files, put it in a .cpp or a .inline.hpp file.
• .inline.hpp files should only be included in .cpp or .inline.hpp files.
• All .cpp files include precompiled.hpp as the first include line.
• precompiled.hpp is just a build time optimization, so don't rely on it to resolve include problems.
• Keep the include lines sorted.
• Put conditional inclusions (#if ...) at the end of the include list.
