G Options

• g, Zi, Z7
  Tells the compiler to generate full debugging information in the object file or a project database (PDB) file.
• g0
  Disables generation of symbolic debug information.
• GA
  Enables faster access to certain thread-local storage (TLS) variables.
• gcc
  Determines whether certain GNU macros are defined or undefined.

• GH
  Calls a function to aid custom user profiling.
• global-hoist, Qglobal-hoist
