WebDec 9, 2013 · This is a fairly standard GCC/Clang configuration, but by no means universal (other 64-bit platforms use other standards). Microsoft, I believe, uses LLP64 as their data model, with long long and pointer being 64 bits, while int and long are both allocated 32. There is even a SILP64 data model - 64-bit shorts, yikes! WebThe main advantage of the clang-built Android ARM (32-bit) hammerhead kernel for my Nexus 5 has been the better battery usage when compared to that of gcc-built kernel, with the same kernel config and hardware (my Nexus 5 Android Smartphone). Details of the same can be found below.

WebSep 19, 2024 · Over the years, there has been a persistent effort to build the Linux kernel using the Clang C compiler that is part of the LLVM project. We last looked in on the effort in a report from the LLVM microconference at the 2015 Linux Plumbers Conference (LPC), but we have followed it before that as well. At this year's LPC, two Google kernel engineers, … WebTarget Triple¶. The basic option is to define the target architecture. For that, use -target .If you don’t specify the target, CPU names won’t match (since Clang assumes … dry turkey brine rub

WebOne way to do it is to use -mfpu=none on clang. But then gcc will complain that none is not valid... And since Qt Creator build the project before the analysis, the build will fail and the analysis will not start. The other way is to define __SOFTFP__. This will force __FPU_USED to be 0 and disable all the functions that use vfpcc. Share Follow WebOct 24, 2024 · I think compiling with clang supports a value of "exynos-m2" (but I've been struggling to compile with clang - another issue). Interestingly, the kernel source I've git cloned used: -mcpu=exynos-m1.cortex-a53, *but* when I start the compile with ether GCC 9.3.0/10.2.0 I quickly hit the error: Web$ cat memory-leak.c # include void *p; int main() {p = malloc(7); p = 0; // The memory is leaked here. return 0;} % clang -fsanitize = address -g memory-leak.c ; ASAN_OPTIONS = detect_leaks = 1./a.out ==23646==ERROR: LeakSanitizer: detected memory leaks Direct leak of 7 byte(s) in 1 object(s) allocated from: # 0 0x4af01b in ... dry turkey brine rub recipe
