2023-07-10add example how to use rtcdWang Chen
Just use vp8_sixtap_predict as example but have not implemented it actually. Test: $ CROSS=riscv64-unknown-linux-gnu- ../libvpx/configure --target=riscv64-linux-gcc $ make Check if vp8_sixtap_predict functions have been replaced with those suffixed with "_rvv": $ riscv64-unknown-linux-gnu-nm ./vp8/decoder/decodeframe.c.o | grep vp8_sixtap_predict16x16 U vp8_sixtap_predict16x16_rvv Check if vp8_sixtap_predictMxN_rvv work. $ qemu-riscv64 -L $SYSROOT_RV64 ./build-test/test_libvpx --gtest_filter="RVV/SixtapPredictTest.TestWithPresetData/*" You should see print log output such as: "--> vp8_sixtap_predict4x4_rvv" "FAILED" is expected due to we have not implemented the actual algorithm.

2023-05-12Don't use -Wl,-z,defs with Clang's sanitizersJames Zern
This avoids link errors related to the sanitizers: https://clang.llvm.org/docs/AddressSanitizer.html#usage "When linking shared libraries, the AddressSanitizer run-time is not linked, so -Wl,-z,defs may cause link errors ..."

2023-05-08gen_msvs_vcxproj: add ARM64EC w/VS >= 2022James Zern
rather than define new targets, add a platform to the arm64 list as they share the same configuration. Bug: webm:1788 Change-Id: Iac020280b1103fb12b559f21439aeff26568fba4
2023-05-08configure: add clang-cl vs1[67] arm64 targetsJames Zern
x86 and armv7 are skipped for now as the intrinsics will need different flags than cl.exe (/arch:... -> -m...). Bug: webm:1788 Change-Id: I8ca8660a8644cdd84c51cb1f75005e371ba8207d
2023-05-02configure: add aarch64 to ARCH_LISTJames Zern
This will allow identifying Windows Visual Studio targets as aarch64; the Microsoft compiler does not define __aarch64__. An alternative would be to define this in the code, checking for _M_ARM64 or _M_ARM64EC. For now we'll use the existing VPX_ARCH_* system. For compatibility VPX_ARCH_ARM will continue to be defined to 1 in this case. Bug: webm:1788 Bug: b/277255076 Change-Id: I12e25710891e86f0c7339ba96884c18ed90ba16f

2023-01-18*/Android.mk: add a check for NDK_ROOTJames Zern
This simplifies integration with the Android platform and avoids the files from being used when a non-NDK build is performed. In that case Android.bp is preferred. Change-Id: I803912146dac788b7f0af27199c7613cabbc9fa0

2022-11-06build: fix -Wimplicit-int (Clang 16)Sam James
Clang 16 will make -Wimplicit-int error by default which can, in addition to other things, lead to some configure tests silently failing/returning the wrong result. Fixes this error: ``` +/var/tmp/portage/media-libs/libvpx-1.12.0/temp/vpx-conf-1802-30624.c:1:15: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int] ``` For more information, see LWN.net [0] or LLVM's Discourse [1], gentoo-dev@ [2], or the (new) c-std-porting mailing list [3].

2022-06-02libs.mk,build/make/Makefile: make test targets ordinary rulesJames Zern
this fixes a regression in make 4.2 and still present in 4.3 causing double colon rules to be serialized which breaks sharding done by the test and test-no-data-check rules. these targets only define one set of rules so ordinary rules work unlike clean. install may be another candidate, but that's left for a follow up. Change-Id: I9f074eca2ad266eeca6e31aae2e9f31eec8680e0 Tested: make 3.81, 4.1, 4.2, 4.2.1, 4.3

2021-11-17MacOS 12 is darwin21Johann
Remove -mmacosx-version-min. The library does not use any calls which are affected by the platform version. There is also no version 10.16 as it went from 10.15 to 11 and now to 12. At some point it may be good to clarify that the bare -darwin- target is for iOS and the -darwinN- targets are for macOS. Change-Id: I2fd5f7cae2637905acf3ab77bfddfbe367abbb68

2020-08-19Escape number sign in MakefilesDaniel Sommermann
Number signs are handled differently in Makefile variable parsing as compared to bash variable parsing. See this demo: ``` $ cat Makefile A=foo#bar B='foo#bar' C="foo#bar" D=foo\#bar E='foo\#bar' F="foo\#bar" $(info $(A)) $(info $(B)) $(info $(C)) $(info $(D)) $(info $(E)) $(info $(F)) $ make foo 'foo "foo foo#bar 'foo#bar' "foo#bar" make: *** No targets. Stop. $ make -v GNU Make 4.2.1 ``` In other words, the `#` character is evaluated first when parsing Makefiles, causing the rest of the line to become a comment. The effect of this is that paths that contain embedded `#` symbols are not handled properly in the vpx build system. To test this change, clone vpx to a directory containing a `#` symbol and attempt a build. With this change, it worked for me on Fedora 31, however without the change the build failed.

2020-08-19Refine MMI & MSA detection for mipsjinbo
