[Openocd-development] [PATCH] arm-jtag-ew: -Wshadow fix
declaration of ‘index’ shadows a global declaration in /usr/include/string.h Signed-off-by: Andreas Fritiofson --- I'm not convinced of the benefit of the warning in this case. A whole bunch of other warnings or error would catch the bug if the local variable index had been used in place of the system header declared _function_ index. I had expected the warning to be emitted only for shadowing of compatible types. --- src/jtag/drivers/arm-jtag-ew.c | 12 ++-- 1 files changed, 6 insertions(+), 6 deletions(-) diff --git a/src/jtag/drivers/arm-jtag-ew.c b/src/jtag/drivers/arm-jtag-ew.c index 7a6c178..72c756e 100644 --- a/src/jtag/drivers/arm-jtag-ew.c +++ b/src/jtag/drivers/arm-jtag-ew.c @@ -568,29 +568,29 @@ static void armjtagew_tap_ensure_space(int scans, int bits) static void armjtagew_tap_append_step(int tms, int tdi) { last_tms = tms; - int index = tap_length / 8; + int index_local = tap_length / 8; - if (index < ARMJTAGEW_TAP_BUFFER_SIZE) + if (index_local < ARMJTAGEW_TAP_BUFFER_SIZE) { int bit_index = tap_length % 8; uint8_t bit = 1 << bit_index; if (tms) { - tms_buffer[index] |= bit; + tms_buffer[index_local] |= bit; } else { - tms_buffer[index] &= ~bit; + tms_buffer[index_local] &= ~bit; } if (tdi) { - tdi_buffer[index] |= bit; + tdi_buffer[index_local] |= bit; } else { - tdi_buffer[index] &= ~bit; + tdi_buffer[index_local] &= ~bit; } tap_length++; -- 1.6.3.3 ___ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
