i'm trying learn basic x86 32-bit assembly programming. in pursuing decided implement quicksort in assembly (sorting integers). first made c-version of sorting function , made assembly version. however, when comparing assembly version c-version (compiled gcc on debian), c-version performs more 10 times faster on array of 10000 integers. so question if can give feedback on obvious optimizations can made on quick sort assembly routine. it's purely educational purposes , i'm not expecting beat compiler makers in terms of producing high speed code i'm interested in knowing if i'm making obvious mistakes hampers speed. the c-version: void myqsort(int* elems, int sidx, int eidx) { if (sidx < eidx) { int pivot = elems[eidx]; int = sidx; (int j = sidx; j < eidx; j++) { if (elems[j] <= pivot) { swap(&elems[i], &elems[j]); = + 1; } ...
