General Optimizer Improvements

  • Support for a new parameter --param case-value-threshold=n ! was added to allow users to control the cutoff between doing switch statements ! as a series of if statements and using a jump table. !

New Languages and Language specific improvements

*************** struct F: E { }; // error: deriving from *** 230,235 **** --- 233,246 ---- instruction set. Previously the GCC compiler did not adhere to the ABI for 128-bit vectors with 64-bit integer base types (PR 48857). This will also be fixed in the GCC 4.6.1 and 4.5.4 releases. + +
  • A new option (-mno-r11) was added to allow AIX + 32-bit/64-bit and Linux 64-bit PowerPC users to specify that the compiler + should not load up the chain register (r11) before calling a + function through a pointer. If you use this option, you cannot call + nested functions through a pointer, or call other languages that might + use the static chain. +
