[PATCH 0/6] eliminate dependency on non-portable __SIZEOF_LONG__

[PATCH 0/6] eliminate dependency on non-portable __SIZEOF_LONG__

[Andre Muezerie]

Macro __SIZEOF_LONG__ is not standardized and MSVC does not define it.
Therefore the errors below are seen with MSVC:

../lib/mldev/mldev_utils_scalar.c(465): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar.c(478): error C2051:
    case expression not constant

../lib/mldev/mldev_utils_scalar_bfloat16.c(33): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar_bfloat16.c(49): error C2051:
    case expression not constant

Turns out that the places where __SIZEOF_LONG__ is currently
being used can equaly well use sizeof(long) instead.

[PATCH v2 4/6] drivers/net: eliminate dependency on non-portable __SIZEOF_LONG__

[Andre Muezerie]

Macro __SIZEOF_LONG__ is not standardized and MSVC does not define it.
Therefore the errors below are seen with MSVC:

../lib/mldev/mldev_utils_scalar.c(465): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar.c(478): error C2051:
    case expression not constant

../lib/mldev/mldev_utils_scalar_bfloat16.c(33): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar_bfloat16.c(49): error C2051:
    case expression not constant

Turns out that the places where __SIZEOF_LONG__ is currently
being used can equally well use sizeof(long) instead.

BITS_PER_LONG etc should be in rte_common.h not scattered
all over these drivers.

Makes sense. I'll update the series, but will limit the additional
changes to BITS_PER_LONG and BITS_PER_LONG_LONG to limit the
size of this series.

[PATCH v3 0/7] eliminate dependency on non-portable __SIZEOF_LONG__

[Andre Muezerie]

Macro __SIZEOF_LONG__ is not standardized and MSVC does not define it.
Therefore the errors below are seen with MSVC:

../lib/mldev/mldev_utils_scalar.c(465): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar.c(478): error C2051:
    case expression not constant

../lib/mldev/mldev_utils_scalar_bfloat16.c(33): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar_bfloat16.c(49): error C2051:
    case expression not constant

Turns out that the places where __SIZEOF_LONG__ is currently
being used can equally well use sizeof(long) instead.

v3:
 * added prefix RTE_ to BITS_PER_LONG* and moved them to rte_common.h
 * defined PLT_BITS_PER_LONG* in drivers/common/cnxk/roc_platform.h to
   avoid warnings from checkpatches.sh like:

   Warning in drivers/common/cnxk/roc_bits.h:
   Warning in drivers/common/cnxk/roc_ie_ot.h:
   Warning in drivers/common/cnxk/roc_ie_ot_tls.h:
   Use plt_ symbols instead of rte_ API in cnxk base driver

   It can be seen that the same was done in the past for similar
   macros like PLT_CACHE_LINE_SIZE

v2:
 * fixed typo in commit message

[PATCH v3 4/7] drivers/dma: eliminate dependency on non-portable __SIZEOF_LONG__

[Andre Muezerie]

Macro __SIZEOF_LONG__ is not standardized and MSVC does not define it.
Therefore the errors below are seen with MSVC:

../lib/mldev/mldev_utils_scalar.c(465): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar.c(478): error C2051:
    case expression not constant

../lib/mldev/mldev_utils_scalar_bfloat16.c(33): error C2065:
    '__SIZEOF_LONG__': undeclared identifier
../lib/mldev/mldev_utils_scalar_bfloat16.c(49): error C2051:
    case expression not constant

Turns out that the places where __SIZEOF_LONG__ is currently
being used can equally well use sizeof(long) instead.

Inside 
There are macros: RTE_GENMASK64 (and RTE_GENMASK32).
Which as I understand does same thing.
Might be better to just use these ones instead of hand-crafting
same thing over different PMDs.

I agree. I can submit a separate patch for that once this series aimed at
unblocking MSVC from being used on this code goes in, if that is OK. If
instead you feel strongly that this change should be made as part of this
series let me know.
