* util: use *unsigned* ints for bit operationsEric Engestrom2018-10-231-1/+1
| | | | | | | | Fixes errors thrown by GCC's Undefined Behaviour sanitizer (ubsan) every time this macro is used. Signed-off-by: Eric Engestrom <[email protected]> Reviewed-by: Eric Anholt <[email protected]>
* util/bitset: include util/macro.hChristian Gmeiner2018-06-151-0/+1
| | | | | | | | | | BITSET_FFS(x) macro makes use of ARRAY_SIZE(x) macro which is defined in util/macro.h. Include it directy to make usage more straightforward. Fixes: 692bd4a1ab9 ("util: replace Elements() with ARRAY_SIZE()") Signed-off-by: Christian Gmeiner <[email protected]> Reviewed-by: Eric Engestrom <[email protected]>
* util: Include bitscan.h directlyIan Romanick2018-03-291-1/+1
| | | | | | | | | | | | | | | Previously bitset.h would include u_math.h to get bitscan.h. u_math.h lives in src/gallium/auxiliary/util while both bitset.h and bitscan.h live in src/util. Having the one file directly include another file that lives in the same directory makes much more sense. As a side-effect, several files need to directly include standard header files that were previously indirectly included. v2: Fix build break in src/amd/common/ac_nir_to_llvm.c.

* util/bitset: Make C++ wrapper trivially constructible.Francisco Jerez2018-02-271-17/+20
| | | | | | | | | | | | | | | In order to fix a build failure on compilers not implementing unrestricted unions, which is a C++11 feature. v2: Provide signed integer comparison and assignment operators instead of BITSET_WORD ones to avoid spurious ambiguity warnings on comparisons with a signed integer literal. Fixes: ba79a90fb52e1e81fb "glsl: Switch ast_type_qualifier to a 128-bit bitset."
