commit 5c9569123793a2e64c633acc5f5ba503871ed16f
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 5c9569123793a2e64c633acc5f5ba503871ed16f
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 3b3975fc9ef622ab4ae407a844e32d1842ac6632
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit cd6f1bf2d5aaa915f9cf83ec1d1ebcf640ad6973
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 10583821fb8872ad5f6a9efd8d565d01e261b0a2
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 7ea64470394c3df1d22fb1ad2ecc674b439d0889
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 8a51cbce7d3a71b0d8987a8a75a99079f2918cd3
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 58f83857188299676423c31496f9882e80af0458
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit d8c50d32c46758cc591fc04e17b5c425ddce78d1
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 3ffff5916a369f26db733dbcdb06c13c7b0c3a68
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 541a2a108e2b0d61cfd70710d7ca4a9a5b5df46e
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 541a2a108e2b0d61cfd70710d7ca4a9a5b5df46e
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 74b7463ab2fb5ab8a87f46c829e62057cc8e2d11
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit 74b7463ab2fb5ab8a87f46c829e62057cc8e2d11
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Thu Mar 3 12:11:11 2022 -0300
Replace internal usage of strtol and wcstol for internal alias
To clean up the exported headers to have only one function prototype
with the ABI aliais (if any) it requires to use the internal alias
for all symbols, since to redirect the internal usage a new it
requires to redirect the symbol with an extra prototype (which this
patch tries to avoid).
The atoi is replace with __strtol due the optimization on stdlib.h.
Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.
