| * compiler_rt: Import popcountdi2.c and popcountsi2.c filesLionel Debieve2020-01-201-1/+4
| | | | | | | | | | | | | | | | | | | | | | Imported from the LLVM compiler_rt library on master branch as of 30 Oct 2018 (SVN revision: r345645). This is to get the __popcountsi2(si_int a) and __popcountdi2(di_int a) builtin which are required by a driver that uses a __builtin_popcount().

| * compiler_rt: Import aeabi_ldivmode.S file and dependenciesLionel Debieve2020-01-021-4/+7
|/ | | | | | | | | | | | Import aeabi_ldivmod.S with divmoddi4.c and divdi3.c from the LLVM compiler_rt library on master branch as of 30 Oct 2018 (SVN revision: r345645). This is to get the __aeabi_ldivmod builtin, which is required by a patch using signed long long division.

* compiler_rt: Import lshrdi3.c fileSandrine Bailleux2018-11-061-1/+2
| | | | | | | | | | | Imported from the LLVM compiler_rt library on master branch as of 30 Oct 2018 (SVN revision: r345645). This is to get the __aeabi_llsr() builtin, which is required by a subsequent patch that uses a logical right shift operator in AArch32.

* Import ctzdi2.c from LLVM compiler-rtSandrine Bailleux2017-07-261-1/+2
| | | | | | | | | | | | | | When using __builtin_ctzll() in AArch32 code, the compiler may translate that into a call to the __ctzdi2() function. In this case, the linking phase fails because TF doesn't provide an implementation for it. This patch imports the implementation of the __ctzdi2() function from LLVM's compiler-rt project and hooks it into TF's build system. The ctzdi2.c file is an unmodified copy from the master branch as of July 19 2017 (SVN revision: 308480).

* Hook up LLVM compiler-rt in the build systemdp-arm2017-05-121-0/+34
This patch enables compiler-rt for the AArch32 target. The code is not used for AArch64 as the architecture supports the 64-bit division and modulo operations natively. Change-Id: I1703a92872b0bb56ac0b98c67193830683963b13 Signed-off-by: dp-arm <dimitris.papastamos@arm.com>
