In parameter passing by 'Name' (e.g. Algol 60), how are formal parameters evaluated?
Pass-by-Name substitutes parameter expressions lazily, re-evaluating the expression (via compiler-generated parameter routines called thunks) on every parameter access.
In target code generation, what is the 'Next-Use' information used for?
Next-use analysis tracks the next statement where a variable will be read, aiding optimal register replacement decisions.
What is the function of the Instruction Scheduler in a compiler back-end?
Instruction scheduling rearranges independent machine instructions to hide functional unit latencies and prevent pipeline hazard stalls.
Which compiler back-end component translates intermediate code trees into target machine instruction sequences using tree pattern matching?
Instruction selection matches target machine instruction patterns against Intermediate Representation (IR) tree tiles to produce efficient assembly code.
In typical C-like runtime organization, initialized static/global variables are placed in which memory segment?
Initialized objects with static storage duration are typically placed in the static data segment. Uninitialized static/global objects are commonly placed in the BSS segment, which is often treated as part of the static-data area.
