[Ada] Spurious range check with Initialize_Scalars

This patch modifies the expansion of default-initialized array objects when pragma Initialize_Scalars or Normalize_Scalars is in effect to suppress the generation of checks on the constructed in-place aggregate. The aggregate intentionally contains invalid values which may not necessarily fit the c

[Ada] Spurious error on fixed-point operation whose operands are expressions

This patch fixes a spurious error in a fixed-point operand of a multiplying operator M when the operand is an adding operation and the context imposes a different fixed-point type to the result of M. Tested on x86_64-pc-linux-gnu, committed on trunk 2018-05-25 Ed Schonberg gcc/ada/ *

[Ada] Improve performance of conversion from String to Long_Float

Once it is sure that the result will be infinity, stop computation and return the result. This ensure that the function call duration is bounded. Before that change on some cases the computation was taking more than a few seconds. Tested on x86_64-pc-linux-gnu, committed on trunk 2018-05-25 Nico

[Ada] Remove 2GB secondary stack limit for 64-bit processors

This patch removes the restriction introduced recently that limited the size of the secondary stack to 2GB. The size of the secondary stack is now limited to half of the size of the memory address space for the target. Tested on x86_64-pc-linux-gnu, committed on trunk 2018-05-25 Patrick Bernardi

Hi. As mentioned in the PR, it's not clear which BB removal are we seeking for. Thus I would remove that scan. The test-case works on x86_64-linux-gnu. Ready for trunk? Thanks, Martin gcc/testsuite/ChangeLog: 2018-05-25 Martin Liska PR testsuite/85911 * gcc.dg/tree-prof/upd
