* PR #1509: Allow building when targeting WASIGravatar Anuraag Agrawal2023-08-15
| | | | | | | | | | | | | Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1509 WASI is similar to emscripten, providing a syscall layer to WebAssembly focused on server side applications. There are some config knobs that are in place to allow building the repo for emscripten which also need to support wasi (as built with LLVM). Aside from that, there are still some features it supports less than escripten, for example related to signals, causing the build to be even more limited for it.

* Optimize Swissmap Match on Arm.Gravatar Connal de Souza2023-08-04
| | | | | | | | | | | | | | | | | Currently we require only a single bit to be set in each abstract bit for iterable bitmasks. However, in most cases, where we have a single match, or no matches in a group, iteration is not needed. We move the masking to the iteration function instead of having it as a requirement for iterable Bitmask construction. This is 4-8% faster for Find and Insert operations. This can hurt performance if we need to iterate many times (there are many matches in the same Group), however this is unlikely, even if we assume the table is completely full. If there are 0 or 1 matches in a group, or the first match is the correct item we are looking for, we save 1 instruction/cycle (most cases) If there are 2 matches in a group, and the first is a false positive, this is neutral (< 3%) If there are more than 2 matches in a group and the first two are false positives, this can be slower by 1 cycle/instruction per additional iteration (< 0.1%) No change to x86.

* PR #1498: Fix order of link options in pkg-config filesGravatar Stan Hu2023-07-31
| | | | | | | | | | | | | | | | | | | | | | | Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1498 In Windows, a few libraries (`dbghelp`, `advapi32`, and `bcrypt`) are added via link options. However, the .pc files produced for pkg-config erroneously include them before the abseil libraries. This can cause undefined references when trying to build against abseil. This commit swaps the order and adds the custom link options after the abseil dependencies. The following is a list of `.pc` files affected by this and the additional link options used: * all: `-L${libdir}` * `absl_base.pc`: `-ladvapi32` * `absl_random_internal_seed_material.pc`: `-lbcrypt` * `absl_symbolize.pc`: `-ldbghelp` Closes https://github.com/abseil/abseil-cpp/issues/1497 Merge af61f6d5d5fa7b390fc2e009652cd6da68b0fd38 into c9c0fd5185067208e1cc4227d16122571762af39 Merging this change closes #1498 COPYBARA_INTEGRATE_REVIEW=https://github.com/abseil/abseil-cpp/pull/1498 from stanhu:sh-fix-pc-link-order af61f6d5d5fa7b390fc2e009652cd6da68b0fd38 PiperOrigin-RevId: 552564626 Change-Id: I9d2a6ab99993bb4315dc94eade2cd419f1109c13
