With reference to the previous query, I think, i miscalculated the offset, just recalculating. 1. without instruction combining coupling member variable, is at:   %struct._FRAME_DATA* %2, i32 0, i32 5   where "%2" is defined as:   %arrayidx3 = getelementptr inbounds i16* %Data, i32 1024, !dbg !446   %2 = bitcast i16* %arrayidx3 to %struct._FRAME_DATA*, !dbg !446 i.e. at 5 offset in

...the code generated "with instruction combining" is: %coupling = getelementptr inbounds i16* %timeData, i32 1060, !dbg !575   %24 = bitcast i16* %coupling to i32*, !dbg !575   store i32 0, i32* %24, align 4, !dbg !575     The FRAME_DATA, is defined as: typedef struct _FRAME_DATA {   Word16 nScaleFactors;                    /*!< total number of scalefactors in frame */   FRAME_INFO frameInfo;                 /*!< time grid for current frame */   Word16 domain_vec[MAX_ENVELOPES];  /*!< Bitfield containing direction of delta-coding for each envelope */   Word16 domain_vec_noise[MAX_NOISE_ENV...
